There is a question that has been in the back of my mind for years about the 6.2. They are designed to fit into the same space that a BBC would right, they were meant for economy right, so why were they never put into cars. Even a full size 4 door sedan in the 80s would have weighed at or less than a pickup or suburban. Seems liked combined with the 700R4, less weight, no towing and thus better highway gears, the 6.2 would actually do very well in providing good power and mileage. So why were they never offered this way? Is it because of the failure of the 5.7 diesel which was offered in cars?

As a diesel mechanic I know that diesels are more efficient than gassers and I believe that this country should have more diesel cars on the road. I love the simplicity of the 6.2 and think that it is a great motor for what it was intended to be for: a good mileage, high longevity engine. I have toyed with an idea for a while and honestly have never dared to mention it before. I guess the fear of getting booed at and WTF were you thinking, type comments have kept me from talking about it. But it is still something I would like to at least honestly consider. And figuring how much you all appreciate the 6.2 figure that this idea might go over better here than on other sites.

What if one was to put a 6.2 into a classic styled car from the muscle car era and make it into a good reliable cruiser with plenty of power for cruising and good mileage? Now I understand the sacriledge thoughts of doing this to a nice origional car and I wouldn't do that. But I have a 71 Camaro RS that needs a complete restoration, lots of new sheet metal and it is far from being anything colectable other than the body style. My goal is to have a car that I can hop in and take on a cross country trip with no worries, but that will also get mid to high 20s in mileage. I have small blocks, big blocks and have even considered an LS swap or even a Fbody 3800 V6. But to be honest, I get tired of seeing the same old thing in a classic car. It seems that people have gotten away from the roots of hotrodding and doing something just to be different. I think that in a lighter car (3400lbs roughly) with a 700 trans and highway friendly gears I could get really good mileage, still have enough power with the torque of the 6.2, would be different, and it is a fitting application that GM should have done. Not neccessarily in an Fbody but as a car engine.

I don't have the need or desire to have a super powerful engine, it won't be raced, just driven.... a lot.

So as I don my flamesuit, what say you oh wise ones have I totally lost my mind or would this be a cool concept? Please chime in.
 
Well, myself owning 7 second gens (mainly parts cars and potential somedays), SCREW YOU!


Actually, i think that would be a cool idea, i say do it. Be unique and still all bowtie :usaflag:
 
Search the web,you'll see many cars,including a corvette and a 59 Impala sporting a 6.2 transplant!...why not,they fit and bolt in,right??..

I think GM missed the boat by not offering them in their full sized RWD cars,the 4.3 V6 diesel never caught on,and the 350 Olds diesel was one of their biggest turds...a mistake from the get go!..
 
:D That is the type of response I figured I would get. But I honestly understand it because of the type of car. I origionally had this idea probably 13 years ago. I had a pos mid 80s V6 Monte Carlo that MAYBE! got 8 mpg. I kept thinking how it sucked that my grandpa's 82 longbed 6.2 with 300K miles got twice the mileage the Monte did.

Now to be honest I am past the need for a high horsepower ride. I have had that when I was younger (18 yrs old, straight out of basic with a supercharged 99 LS1 Corvette thanks to Uncle Sam!). Now I really just want a dependable ride with classic looks that the whole family can ride in. But I don't want to have something so valuable I am afraid to drive it. And I would like something to make people's heads turn when they see it. That is always the most enjoyable thing for me at a car show is to see something unexpected.

Now the story on the 71RS. It has a TON of bondo on it rusted floors, quarters and trunk. At some point in the 80s someone put a carpeted 76 T/A dash in. It is a factory RS V8 car but just a simple 307 nothing special other than the RS front end. It has sat in a field for over 15 years. So I figure if I restore the body, at least I am putting another cool looking Chevy back on the road. Because of this I have decided to have fun with the build when it begins. I have a 97 firebird parts car for the interior (dash, door panels, seats, etc) I figure if I am going to build it I will do it with all the (my opinion) best looking parts. So when it comes to the engine I figure why not the 6.2, maybe even with a turbo. It should fit in the engine bay easy enough, have plenty of power for a good cruiser with good mileage and great style. Plus it would really stir the pot at cruise ins and car shows.

Seriously though anyone know why these engines were never put into the cars of the era?
 
:D

I would say emissions and nobody really liked diesels back then, and it would have been third gen before camaro got it, and they didnt think camaro and fuel mileage haha, camaro=performer car typically.


Are you a member of nastyz28? Im kansastwister there too, i think i saw the 71 with a poncho dash, and i liked the dash lol. One of the things i like about the firebirds and transams, but i cant decide if i like those dashes or the 79-81 camaros better.
 
Yeah I am, that's it. I would dare suggest this engine over there though, I might get banned. I know it would have been thirdgen to get the 6.2 just wondered why they didn't at least put it in say a Caprice or something. I hadn't thought of the emissions as a cause though.

If you do enough searching you will see the 6.2 put in pretty much evry kind of car, I know a guy that was putting it in a 55 chevy shoe box.
It never was put in cars for the same reason no other manufacturer is or has offered diesel cars in the states: They think it will not sell and they still want to balance the fuel consumption between diesel and gasoline. Gasoline is a byproduct of diesel refining and they need to sell it just as much as the diesel fuel, there are already enough trucks and machinery that use diesel, they figure why switch people to diesel cars, we will never get the gas sold, and that would upset lots of people.
The other issue had been smog, but technology has since evolved that diesel emissions are cleaner than gas.
I am putting a 6.2 in every vehicle I have jeeps, chevies, dodge, I think I will keep my 67 firebird stock because of it's value but that is it.:D
 
You wouldn't get banned, heck if your worried ill suggest the idea saying i know a guy who is talking about a 6.2 in his 71, wont even mention your name, if they gather the villages with torches, well keep your head low :haha: But i think some of them will be interested, ive never really worried what others think, id rather be the lone wolf.
 
Well I meant the banning part as a slight joke. Honestly I think most people think camaro=sports car. Many forget it also came with just a straight six, so the thought of doing something other than a performance build doesn't even seem logical to most people. I will probably bring it up there after I make my final decision.

The 97 firebird I got for parts($300) has the 3800/4l60e in it unknown condition. But right now the radiator/fans/condensor are missing, and for some odd reason somone cut the fuel lines where they connect to the engine rather than using the proper tool to unhook them. Otherwise it is complete minus some interior pieces, a headlight and a fender. I have some new (used) fuel lines on the way. I am going to see if I can get the car running/driving. Then make the final decision as to which engine to use in the 71. If I can get it running I would honestly consider the 3800 V6, but the 6.2 just seems so cool to me. I will probably just end up sell the v6/trans and other parts from the car to buy a 6.2/700 combo. I just want to commit mentally before I bring it up over there.
 
Duramax! Google that along with car transplant. There are several really cool swaps using the new diesel's, including an impala and a chevelle I believe. They also use them on airboats, off shore race boats, etc. Someone out there makes a high RPM version and dry sump oiling for ground clearance. I love the idea, and have been thinking of a build like that for a long time.

I could definitely see doing an Isuzu 4BT into a standard cab, short bed, 2WD mid 80's chevy truck (dropped, tubbed, pro street style), and using that for commuting. Should net great mileage, be super simple, and not be a dog. I also thought the 6.2 with a turbo would be a good candidate for a swap like that. Bolt right in, use a 5 speed stick (NV4500 2WD). Right now though it's a pie in the sky...too many other projects going on.

My latest project is an Expedition type vehicle (think Sportsmobile). I'm picking up an '06 GMC Savana Cargo, 135" wheelbase, with the Duramax. I'm all for diesel swaps and crazy ideas. Heck, what did people say when Carol Shelby stuck those big Ford V8's in those little AC cars? My other project is a 240Z with a V8 (taking up garage space right now).
 
Ya know a T56 came behind the LT1 small blocks. It would bolt right up to the 6.2 :thinking: At least then it would fit the old adage of "sports cars have manual transmissions" No I will probably stick with just a 700 (I have a couple laying around) The more I think about the 6.2 swap into the Camaro the more I am liking it. Funny thing is I guess I have never seen a 6.2 painted and detailed nicely. Anyone have pics of one? Can someone remind me the dressed weights of a 6.2, 454, and 350 so I can compare them. It would definately be easier to adapt into the older car when it comes to the fuel supply I think the gas fuel sender can be used from the 71 so I would just be looking at possibly a bigger filler neck. Lots easier than trying to put a fuel pump in tank for a gas fuel injection system.
 
I have a TKO600 (5-speed) in the Z. Was thinking that'd be a great tranny for a swap (smaller and lighter than the T56). It's also capable of handling the power, and has good gearing. Bolts right up to a standard bell housing too. I have a hydro-throwout bearing, easy to set-up!

Can the T-5 (was it the World version, is that the right name?) hold up to the torque? Small, cheap, shift well.

Either way, if you want better mileage, stay with the stick. Especially in a sports car. Don't need a tranny cooler either...just simpler I guess.

There was an article written by a diesel mag about a 6.2L build-up a few years ago. I have the printed version, but here's the online link:

Have fun!

I don't have the numbers handy but yesterday I was moving my 6.2 engines as well as my 400 SBC and my 396 BBC, and I can say the BBC weighs more, the diesel is next and the 400 SBC is the lightest.
The engine hoist was tipping with the BBC but not with the other 2.
 
go tko not t56 if you go manual, the t56 his a problem with STOCK shifter location, you have to cut out the floor support brace.
 
I think it would be a pretty cool swap. With just a few tweaks I would think a N/A 6.2 would have plenty of power and get great fuel mileage in that car. With a nice sounding exhaust nobody would even know it was a diesel unless they walked right by it while it was idling.
 
I say do it.

You'll find that overseas this wouldn't raise nearly so many eyebrows. I believe it's The Diesel Page's galleries but at any rate one of the forums that does 6.2L/6.5L diesel stuff and has galleries has/had pictures of several 6.2L into car swaps including a Canadian with a Corvette with a 6.2L shoehorned into it, a...Swede?...Scandinavian at any rate...with a 80's GM big station wagon with a 6.2L, and a Spaniard with a 6.2L in a GM bubbletop sedan from the early 60's.

Hell, I've seen 6.2L's in Toyota Land Cruisers and even a 80's TTB Ford Bronco over in Australia.

Everywhere else it was the only commonly available American big diesel that fit into passenger vehicles and used common transmissions and parts. It got used, and liked.
 
Wonder if I could get a tax credit for building a "green" car? :D I know a lot of people will not like it. SCREW THEM, it's my car and having it running down the road looking good is better then it sitting in a field rotting. Or winding up as a dirt track car. I really dont understand the american hangup on diesel cars. Power should be fine since it is a little better than the 307 with better low end tq. Perfect for a cruiser which is just what I want. I'll just have to buy a TON of sound deadener. Any body know for sure if a gass fuel sender can be used in a diesel conversion? Seems like I have read in the past that it can be it just wouldn't have the water in fuel sensor. Is there a way to add a sensor to the tank seperatly?
 
You could probably graft a factory sending unit from a diesel pickup into the Camaro tank ,or at least the water sensor portion of one..or add an aftermarket one.

I'm willing to bet a 6.2 in a Camaro with a manual tranny or 700R4 would not only perform admirably,it'll get 20+ mph easily too..I'd say any tranny they used with a 350 V8 will hold up behind a 6.2..the automatics behind a diesel used a 6 bolt torque converter with slightly lower stall speed,but I know of a few guys who just bolted a 700r4 from a gas powered truck with the typical 3 bolt converter in them using only 3 out of the 6 bolts,and haven't had any issues,and didn't really notice any big change as far as the stall speed..
