Got any details on how you rigged an LS1 computer to work with the Hemi? After driving my Magnum RT for the past year, I'm seriously considering swapping a 5.7 into a 67-69 Barracuda.

I Also Own A1968 Camaro With An Ls6.and I've Several Harnesses Thru The Years So I Am Pretty Comfortable With The Ls1 Gm Stuff.i Just Like The Way It Is Obii Compatible And You Can Pick Up A Computer And Harness On Ebay For About $300.to Be Truthfull Though It Was Not Easy, Had To Machine The Gm Reluctor Ring To Fit Hemi Crank, Make Adapters For Throttle Body And Cam Sensors. So The Engine Has To Be Disassembled.it Would Be Easier To Run A Fast System If You Can Afford It.i Installed A Comp Cam And Springs ,tti Headers And Msd Coils 16 Of Them!!!but It Looks Cool And Makes Unbelivable Power

(v)opar all the way

What ya got against the magnum motors? My puny little 408 maggie make over 400 to the wheels on crap CA pump gas, with Iron heads and all that CARB crap to boot. I like the fact they use a roller cam stock and you can run any LA head as well.

A nice build, R3 block, 340 mains with 4" stroke, 4.155 bore, make sure it has the 18 bolt heads. W5 heads (if you can find them) and W5 intake, drilled for EFI. You could make 600hp on pump gas no problem N/A, drop the compression, add a pair of GT42R's and 800 isn't a far stretch

Big blocks are old and busted and generally way too heavy

If you want something really nasty there was a post on a mopar board where a guy is selling some 358ci pro stock truck motors. R4/P5, top dollar builds for less than those heads cost new.

Magnums Are Cool,have One Of Them Too.but What Other Engine Can You Pull Out Of A Wrecked Car, Stick An Off The Shelf Cam And Headers On And Make Just This Side Of 500 Horsepower , Get 20 Mpg And Have Great Road Manners?beats The Ls Series Chevies And The Ford Mod. Motors

my only issue with the new hemi's is you have to use a slushbox, and that just isnt happening in my car

That all depends on the tranny/transaxle you want to use, and how much your willing to spend.

Also has anyone confirmed the hemi doesn't use the same bellhousing pattern as the LA/Mag motors? or even better yet the same as the V10/diesel?

[57hemicuda]

The Hemi Does Have The Same Bellhousing As A Smallblock Mopar,i'm Using A 727 In My Cuda Works Well, But Any Smallblock Bellhousing Will Bolt Up. The Only Difference Is Block To Crank Spacing Is About .100 Taller On The Hemi.you Can Get A Manual Flywheel Right From Chrysler, So That Won't Be An Issue.i'm Already Squirrling Parts Together For A 70 Cuda Hardtop I'm Going To Put A Stick In

Sweet so toss a T-56 behind that new hemi and your ready to rock .100" won't be hard to fix, either shave the BH or cut a spacer, not the end of the world.

We are working with a new business that is doing an engine management setup for the later HEMI engines. Their controller seems to be pretty good, very tunable, and they are doing a great job wringing out power from the HEMI crate motors (510 HP with a cam swap and some mild head work).

The car we are building to develop the suspension system is getting a stroker 440. It is a big heavy motor, but it is also a big heavy car (B-body), and it will make big, heavy power. We are looking well into the 650 HP area on pump gas, with nothing terribly exotic. It'll use Indy heads and intake, stock block, and a roller cam. Bang for the buck, on this car, it can't be beat in that we already have a good block. Should be a lot of fun.
