No, I mean a 1/2 ton pickup or blazer. I would like to hear what the crew cab 1 ton guys get with the 6.2.

I was being a smart azz... cause that is my other idea... 6.2 into a S series pickup.rjfguitar said:
But, I really miss dd a full size truck. So, I am kind of torn between the two ideas.
I actually broke the 20 MPG mark yesterday when I filled up 
Got 21.5 MPG average over the last 450 miles. 
I think I'm going to keep the 4.10's and 285/75R16's just for the extra power I get for hauling a load. Long term plan will be to add an overdrive that allows me to split gears for the bigger hill climbs.

I got around 16 with the auto. With the 4 speed its probably gonna go up slightly, but not much. This is with 34" tall tires and 4.10 gears.
A 6.2 powered s- series pickup would be pretty cool. A serious redo of the front suspension would need to be done to carry the weight.four_by_ken said:

I doubt it would take much. People put big blocks in them quite often without trouble.rjfguitar said:
I have no experience with s10's but I bet it would be plagued with wheel bearing problems.joez said:

The front suspension on the S10 2wd trucks is the exact same parts as the mid sized cars like Monte Carlo's, Buick Regals, and Olds Cutlass which I have seen used with big blocks and no front end problems before. They are probably oversized for the S10 but I'd want to consider a stiffer spring to take the extra weight.

No reason to do this. New springs and all is good.Drey said:
I know you said you weren't interested but I will throw out something if you are in search purely for better mileage.
A cummins 4BT would be the best bet. I don't think a 6.2 could match the mileage of a 3.9 litre 4BT. It could match the power of the 6.2 and easily surpass it with a little bombing.

Then you have to get a different tranny, and unless you are spending some coin on a NV4500 or find a getrag you are going to be running an non OD tranny. Not only would you have crap for a top speed, but the motor winding that high wouldnt equate to good fuel economy. The 6.2 can be run in front of a 700R4 with the magic OD, the 4bt cant, there is no converter for it. Sure, you could put it in front of a non-lockup TH400, or a 465, but have fun in the slow lane. Then you have the options of a NV4500 or a getrag, but thats gonna cost money. 4BT's arent exactly cheap either, ive been hunting for one for over 6 months now, people want money for them. You can find 6.2's for free, and it will drop right in place.
While the 4BT would most likely get better economy, that would be offset by the extra cost.
For what he wants to do, the 6.2 is the motor of choise. Its not a tow rig, all he is looking for is easy fuel economy, even though the 4BT is a better motor.
Just on a foot note though RJF, there are people out there in 2wd pickups getting 30mpg with their 6.2.

1973 K10 with a 6.2 and a 4 spd manual with OD (A-833).

I know and agree, it would be a lot of work converting to cummins power. The same argument can be made about converting to diesel power period. Unless he can get a 6.2 for basically free and it only costs a couple hundred dollars to convert....you could make that up in fuel costs in a year or two. You can buy a lot of gas for 200-300 dollars and it would take a long time to make that up. TrustyK5 converted for mileage mainly IIRC and says he is still waiting for the cost of the conversion to be surpassed by the fuel savings. That doesn't count all the labor to convert.Pull that 6.2 out of that light 2wd 1/2 ton and put a 4bt in and watch 30mpg blow out the window. I would put money on it that a 6bt could top 30 in a little light 2wd 1/2 ton. THey get 20mpg and don't come in a pickup lighter than 5,500 lbs from the factory. Not trying to start yet another cummins vs. GM piss match.Just on a foot note though RJF, there are people out there in 2wd pickups getting 30mpg with their 6.2.
Mileage wasn't my only reason for swapping in the 6.2.
So far I've put 14,000 miles on my truck since swapping to the 6.2. I was getting 9 mpg on a good day with the 350 I had, so I would have put 1555 gallons of gas into my truck if I still had the 350. I get 16.5 mpg with the 6.2, or 848 gallons over the same amount of time.
To simplify I'll average the cost of gas and diesel to a nice round $2 a gallon over the last two years. I've saved $1414.00 in fuel costs since I swapped the 6.2 in.
Including the purchase price, rebuilt IP, injectors and other sundry items i'm into my swap for close to $1400 US...so the 6.2 has officially paid for itself already. If I drove the truck more it could easily have paid for itself in under a year.
My main reason for swapping the 6.2 in was off-road performance. I had a carb'd 350, and it sucked with three different carb's and all sorts of different set-up's. Always flood out and stall on hills and stuff. My thinking was the TBI would be cool, but my 350 was tired so I'd have to rebuild plus add TBI...a bit spendy and would still net me ~9-10 mpg. I thought of propane, but again would have to build a 350 and I didn't like strapping a big bomb under my truck.
The first time I got the nose of my truck pointed to the sky with the 6.2 you couldn't have removed my smile with surgery. It just kept purring away, and it'll do twice what my 350 ever would at idle.
Anyways, it wasn't just fuel mileage that got me to swap...but it helped!

They dont have super strong spindles... but the weight differance between a 4.3 and a 350 isnt that big of a differance. I have a 4cyl, but still the same spindles.Drey said:
There are BBC in S-10s around here. Spindles handle it just fine. Need a little work with the springs, but its not a big deal. The 4.3l springs with the 350 work great... for a 2wd that is. Brings it down about an inch.

My thoughts... this is my daily driver. 75+ miles a day. Thats if I only go to and from work, no where else.
I got the truck brand new for $9500. These 4cyl are ok on mileage, I get about 24mpg year round no matter how I drive it.
When it gets time for the engine to go... I highly doubt I will put another 4cyl in there. If I keep the truck, I would love to do a 350 with it. But, for as much as I drive, going down to 13mpg... just isnt feasible.
So, thats what got me into thinking about the 6.2l.
I would love a 4bt much more, but I just dont know what I would do as far as a trans.
6.2l... as stated a 700R4 would work easily.

I have a 5.9l perkins TD in a light weight K5 and I get 30mpg all over except on highway, where I get 22-25 trying to keep up with traffic.
I know if I had a better close ratio tranny and bigger tires I could stay in the 30mpg
