77K5. The IronMaiden...9/2 headed for Blazer Bash 20!

[Deuling]

I just cant see dave the "american muscle" lover put an LS in place of that perty motor...


And IMO the sound a motor makes... IS HALF THE FUN OF IT

Fuel injected big block is pretty cool.

WELL SAID

I can see erics point, but simplicity is with the current motor and adding efi. a 6.0 swap would be cool in bart but he already has a 6.0 in the new truck. so.........

 

[76zimmer]

not sure on the drop air cleaner, I thought it worked fine but I might be remembering a carb swap and not the EFI swap. But our trucks have plenty of room for a flat base aircleaner anyway, even with a big block. My air cleaner has a slight rise to it, with a 4" element, and its fine.

good to hear your 489 runs good with that setup Heath...I've seen you run it through the gears on the dune video....what rpm and how many gears (t/c range and trans speeds) did you use?
I think I need to have full throttle power for at least 45 seconds (thinking of running the dunes at Erics, which have a lot more length to the climb than S/L) so no running short on fuel is a must now. I guess if it will feed 720hp, I'm plenty safe.

Also, I may still build a custom tank as my frame mounting isn't stock anymore either.

from Chevy305's rig it looks like he is running a drop base...

sweet, no new aircleaner needed then.

So playing devils advocate here for a second.

How much could you get a 6.0 for. They really aren't that hard to put in and I have a buddy that does wiring harnesses for not a bad price where it would be a plug and play kind of deal on the electronics.

You would have to mess with the fuel system, but I personally think that would be a better motor in the maiden.

Well what would you do with the motor in the maiden?

Put it in Bart. It was built for torque and while the motor in bart is certainly strong, it does consume oil.

Just trying to throw some wrenches in your works Zim

The 6.0 can go over 400 hp easy. Just depends on how much you can find one for in a wrecking yard and how many miles etc it has on it, that will decide the overall cost. And it may well end up costing more than fuel injection on the big block. But I kind of think not

this has all crossed my mind in the same scenario's Eric...I could probably get the 6.0 into the Maiden, for the price of the FI system by the time its on the truck....come the day to build another rig, safety, light weight, articulation, hp, and reliability will be keys to that build....right now I have a tank and the 465hp/550tq is king!

And oh yah the stock fuel tank baffles work pretty darn good. I have been at some pretty extreme angles. Enough my oil pressure has gone to zero and the motor was still running.

It was only about 6" difference to where I was sitting and had oil pressure to where I got to and had no oil pressure, they pulled me back down a couple inches with the winches and Horton sat there and ran for 15 minutes without missing a beat.

I had about half a tank

I went through about 3 gal/hr on the trails in Moab last year....not sure how that compares with other BBC's maybe Keith keeps track of his, but I think the 30gal tank will have to be required, and maybe a jerry can too!

Good to hear on the baffles Eric, I almost said ask you because I am sure you've had it at more extreme angles! No offense of course!

It actually sounds like it works too good, I'd rather lose fuel pressure before oil pressure.

As for the 6.0, are you smoking crack? You want him to downgrade from a fresh big block to a small block? A 6.0 at 400 hp won't have as much torque as that BB at 400 hp, and that big block most likely has more than 400 hp, especially if he gets an RPM intake.

Also, look at it this way, you want him to put his carbed big block in the tow rig, and then swap a stock small black in his wheelin' rig? huh?

Heath thinks like I do!

Best thing I ever did to my rig is make it lighter, thats the reason I almost always will favor a smaller motor. The 6.0 is plenty capable of making great power. Obviously a big block will have more grunt. But a 6.0 will rev higher and still make great power.

I really just wanted to throw it out there as another consideration, I realize conventional car guy wisdom says going from a big block to just about anything else is nothing short of sacrilege. But losing weight in an off road rig becomes very important the harder stuff you try. I realize you guys have different wheeling out there for sure, when crawling the only thing a big block does better than my small block is sound better

I'm sure you've got about a ton less weight than I do Eric, I ridden with you and know what Horton can do...simply amazing! And maybe I should incorporate selective cylinder management into the programming??? as it only takes 100hp to rock crawl!

I was pretty happy to sell my mild built 454 so I can swap to a 6.0 or 5.3.

And save about 300lbs too right?
As I mentioned above Matt, I think I would be headed the same route you are if starting all over again!

I think it has a lot left on the table too Adam...this tuning exercise should help bring out the best in it!

Like I said Dave it was me I really doubt I would be taking a rockin big block out of any truck I owned.

But just wanted to throw that out there.

Just so you know I know a guy here in town. Little bowl work on the heads, higher ratio rockers( might have a mild cam too) and a tune, on a stock 100k (seasoned he calls it) bottom end and he is putting down 495 hp and 505 lbs feet of torque. Not sure what the RPMs come in at definitely higher than a big block. He took out his 572 to put it in there. Pulling it this winter to reach his goal of 600 hp. Not going to take much more he is bumping compression a bit then lots of tuning should have him over his 600 hp goal

I know other guys who have rebuilt them and messed around with other things a bit more that are putting out will over 550 hp and over 500 lbs feet of torque.

I realize its a different type of power but those motors can be easily built to way out preform a decent big block.

Now back to the big block goodness

I wouldn't doubt any of that Eric, when I started this truck build, anything electrical scared the living hell out of me....I could barely figure out a non working turn signal, now with the help of my buddy Tony, I'm getting a little braver...in another couple years I'll be doing Duramax swaps in my sleep!

Really I'm impressed with the 6.0's ability in my 99, and I know thats a 220K mi 300 hp version...I was amazed it didn't complain at all hauling the Maiden out to Moab last year (except for the elevation)...I'm sure it was about 2K over its rated tow rating....but it just did it!

A non logical thinking part of me ...wants to say fok the gas prices, I'm not afraid of running dinosaur old school big block engines...either.

 

[blazinzuk]

.in another couple years I'll be doing Duramax swaps in my sleep!

I will start saving money for your plane ticket now then

well I could do it, just don't expect good results..

 

[max 02]

Come on Dave!
Russel said it was easy!

 

[yellowK20]

It's all about compression ignition, the gas burners are to inefficient . Duramax the maiden........

 

[76zimmer]

Come on Dave!
Russel said it was easy!

OK Dean, bring that HD of your's down and we'll give it a go! But it would have to go in BART, not the Maiden!

It's all about compression ignition, the gas burners are to inefficient . Duramax the maiden........

ain't arguing that Gus

 

[max 02]

I don`t think our truck would be very handy without it`s heart!

But I like the idea!

Leave the 454 in the Maiden...Get the fast.
My uncle in BC just put a fast system on his 383,it is in a 68 chev c10 with a 5 speed standard. I haven`t got a chance to talk to him about the install...but he said it`s awesome!

 

[max 02]

Just for fun... the 68.

 

[Deuling]

The fast is pretty awesome from what ive seen. At the hot rod power tour the edelbrock guys had a new fi system in one of there old cars. I talked to them and they said it will be be there version of the fast ez efi setup. Looked super clean and they said they were testing it out on it and said it works awesome... Something to look at if it comes out on the market. (it may have already, i cant remember what it was called though)

 

[y5mgisi]

Are you talking about the atomic EFI one? The one that looks like a holly?

No thats msd. I talked to the guys at edelbrock

I realize its a different type of power but those motors can be easily built to way out preform a decent big block.

I think you have it backwards here. LS small blocks come factory with 15 degree heads with efficient combustion chambers, but there is nothing in them the defies physics. You put 18, 14, or even 11 degree heads on a big block along with a roller cam and then the whimpy little small block is like a power wheels. And even with the factory valve angles more displacement with the same hp is going to give you more torque down low. Is a small block lighter, yes, but aluminum heads on a big block can save 80 lbs. Big blocks parts have changed over the years too. The old saying still rings true, there is no replacement for displacement.

There are many things to help the little engines get closer such as comb chambers, valve angles, cam profiles, turbos, superchargers, nitrous, etc, but do those same things to a larger engine and the larger engine will usually win. Now, stock LS vs bone stock big block, yes, the lighter engine with similar or more power will win. But a big block has way more potential that most people don't even realize the parts are available. built LS vs built big blocks, the big blocks will always be winning, just as they still are if you go to the drags. LS engines are very popular because they are EFI, lightweight, and you can make pretty good power with only a cam swap and headers, the reason is their heads are so darn good from the factory.

car craft i think it was built a 2000+ hp lsx do one of those for the maiden

here you go.

Vic was even there when I was talkin to the guys
