Thank's guy's. By the way, I also drive an 03, Chevy 2500 HD. The way I look at it; After you build a performance motor, all you have left of the oringinal engine is the block. All the internal parts are after market. I'm just trying to find the best HP to $$$ ratio.

 

Isn’t it hilarious how many people start trying to call out the 345 Hemi engine and start talking about how they “beat them so easily”... Yet I have scene half a dozen Hemi Trucks in the 13s with just a handful of Bolt ons.

The other funny thing is how this guy who is trying to have a peaceful transfer of friendly information isn’t even talking about the 5.7 Hemi hes talking about the 6.1 Hemi, yet still gets lit up.

Last Time I checked The 370ci 10.3 to 1 compression mid ranged camed, Iron block 6.1L Hemi dyno tested at 381 RWHP with a slush-box between the engine and the pumpkin....

*People need to lighten up and stop letting a word like HEMI scare them.





P.S.
How many stock LS2s with autos make More Horse Power at the R-wheels than the number of thier cubic inches of displacement.

 

Hemi...scare them?


Here Hemi....Hemi....Hemi....

 

One of the low 12 second Hemis On Juice with stock bottom ends might wake you up though.

Usually with 20s or 22s too LOL!

 

Well, actually I'm taking the 6.1 and stroking it to a 6.4. The 392 cu in stroker, has been dynoed at 510hp NA. Then the supercharger will go on, on top of that. All I was saying is that I just wanted to get the most horsepower to $$$ value. The Hemi excepts the Chevy's, rods, valves, springs and retainers at a fraction of the cost. Some slight machining is necessary to some of the pieces. Still the cost factor is cheaper than buying Dodge specific parts. Right now I'm trying to figure out how to adapt an LS1 intake manifold to the heads. Dodge will sell me one of their's for $3000. See my point? I don't care if you drive a Chevy, Ford, or Dodge. We're all on this site to learn about performance. Bottom line. Horsepower is horsepower, I don't care what color your horse is.

 

Very nicely put. Do you have any pics of your build? I am very interested on how you are doing this. Keep us posted.

 

I also am interested. You said you were trying to adapt a LS1 intake manifold. How are you going to deal with our weird cathedral ports? Or are you using LS1 heads as well? Also, since all the other parts seem to fit, I'm wondering if the pistons will work? Or maybe better yet, vice versa? Heck maybe Dodge has the cure for GM's piston slap problem?

 

Interesting findings! I hope it all works out. Please keep us updated on your progress!

 

I'm using a set of custom, closed chamber Hemi heads, with custom, Calico coated Ferrea severe duty valves. $1200. I waited two months before the valves showed up. It was during this wait when I started to cross reference other valve sizes. I couln't figure out what was taking so long. I found a Chevy intake valve that is the identical size to the Hemi's. With slight rework, I found a Chevy exhaust to fit also. Less than a third of the price. I then started checking on rods. I was told I would need custom ones built, since there were no after market ones available. Another $1200. I looked in a catalogue and found an H beam, forged Chevy rod that will pop right in after $75 of machining. $575 total. I didn't cross reference any pistons since custom Ross pistons are going in. Comp Cams Bee Hive valve springs, for the LS1, is a direct replacement for the for the Hemi's. Manley now makes a Hemi specific valve spring. The LS1 intake idea is still up in the air. I have the drive by wire issue to resolve first.

 

Yea, PIXSSSS!!!! I am real interested as well.... even if I am going to do something else....
