:no

GM trucks do not like mopar engines at all, buy a corvette 427 (LS7). Why bastardize your truck and it is a lot of work changing trans, driveshaft, linkage, mounts and wiring

Re: Hemi anyone? 6.1/ 6.4

It's an interesting idea. A hellcat 6.4 in a c10 would be cool. The problem is more with the cost of swap and performance parts. Mopars are always more expensive to build then a Chevy motor. You can get the same performance from an ls for a lot less. Plus hemimotors are externally larger limiting your useable space.

Agree. What is so great about the modern Hemi anyway? a 6.1 is 425 HP/420 torque. A 6.4 is 470hp and 470 torque. A 6L truck engine is virtually the same output as a 5.7 Hemi-with better fuel mileage. (http://www.allpar.com/mopar/new-mopar-hemi.html)

You can buy a LS based engine for much less that will do the same thing. The LS3 is 430HP/424 torque. If you want the big power (and $$) you can get an LS7 that is 500HP/470 torque or the new Corvette is 450/450.
(http://en.wikipedia.org/wiki/GM_small-block_engine)

Why go to all that trouble to put something in that will fight you the whole way for no gain over what has been done before?

Re: Hemi anyone? 6.1/ 6.4

I don't see anything wrong with the idea except the lack of aftermarket support and all the legwork you would do figuring out the transplant. I will never understand why some swaps in certain vehicles are acceptable and others are taboo. Different strokes, figuratively and literally In this case.

Re: Hemi anyone? 6.1/ 6.4

I can tell you this, it would get a lot more attention than any LS swap would. The comments above pretty much sum up why it isn't very common however.

I would love to put a Hemi or a Ford Coyote engine in a Chevy for no other reason than to piss the purists off. lol

Re: Hemi anyone? 6.1/ 6.4

Re: Hemi anyone? 6.1/ 6.4

That's cuz a Cummins isn't MOPAR... just happens to be yarded out of one.

Re: Hemi anyone? 6.1/ 6.4

It be cooler to swap an older hemi in, the newer ones are not as desirable to retrofit.

That sound's like a torque monster! What is it out of?

Got it out of 64 hearse, even got the yoke in the tranny. Traded a pair of '72 doors and a 2 barrel Holley for it! Got it running, building the truck around it as we speak, need a 55 1/2" drive shaft, steering shaft and master cylinder. I'll get some pics someday....

Re: Hemi anyone? 6.1/ 6.4

I got a 5.7 hemi in my jeep. That thing rocks. Got a 6.0 in my chevy 2500 van. It ouruns alot of cars light to light. To me the 5.7 pulls a little harder mid range.

Re: Hemi anyone? 6.1/ 6.4

For those that haven't seen it yet, the new 6.4 Dodge Hemi Hellcat engine has 707 HP, sitting on the showroom floor.

707 Horse Power and an eight spd automatic.

Re: Hemi anyone? 6.1/ 6.4

It would definitely be cool, just would take a ton of fab work to fit it in there. Not something I'd like to tackle.

The modern Chrysler V-8's seem to be pretty good, in my experience its the trans, rear, and the rest of the vehicle that falls apart.

I read one article where they dyno'd a hellcat challenger and at the wheels was almost 800 hp, all factory...

I've seen quite a few of the newer hemi's having problems with valve seats falling out of the heads, causing valves to hang open and sometimes causing more serious damage. But if you really get technical what engines don't have some sort of common problems these days.

Re: Hemi anyone? 6.1/ 6.4

When my uncle was restoring his 66 k20 he bought a 65 c10 for the cab and it had a 392 hemi in it. Still have the motor and he wants to put it in a willys coupe. There is a guy in Pittsburgh PA selling an original 426 hemi. Just wait for it though.........he wants $10,000 for it and it doesn't run.

The 2 Dodges I owned, the ONLY part that didn't give me issues was the engine. Every other damn thing fell apart, shorted out, failed, leaked, clunked, whined.......

Sell your Chevy, go find a 60's Dodge and put your Hemi in that. You'll be happier.

Re: Hemi anyone? 6.1/ 6.4

well looks like its a go on the 6.4...480hp stock 500hp with a little tune.
it will have a 5 speed auto trans with double OD. and my truck weighs about 600lbs less than a challenger.
the plug and play is a little more than LS motors....but the good is this motor has only 2k miles on it.....makes the swap worth more to me...
