the special carb deal is the carb is being built by one of the best carberator guys in the country and tuned by him on the motor on a dyno that's what is meant by the special carb
Be sure and post an let us know how the tuning works out - it would be great if someone got onto an effective way of running a single carb.

Just some comments after reading this thread that may be helpful. Not trying to be a "know it all", just sharing what I have experienced.
- The Apache heads will fit on a 5.7 block
- Another alternative for good heads is Thitek
- The 5.7 block is a cheaper and more readily available alternative.
- If using a truck 5.7 block you will need to account for the different dipstick location and if using a pan with a dipstick tube you will need to plug the dipstick tube hole in the truck block.
- If using a 5.7 truck block and a 6.1 timing cover and AC you will need to drill and tap 2 holes for the AC bolts in the block.
- To delete MDS just replace the lifters. You can leave the MDS components in place - no need for plugs.
- These engines do not like a lot of timing so be careful.
- Stick with fuel injection and a 6.1 intake for most applications.
- NA or forced induction they can make a decent and reliable HP#
We have a 3700# car, NA, 430ci going 10.0 in the heat and should nick 9's shortly.
We also have a 5300# Jeep, turbo, 370ci going high 9's and daily driven.
These engines are impressive and I can't wait to see when someone really starts pushing them!

Ok guys David Barton did my lifters. I was at his shop and he took them apart while I was there. There is really not much inside them. He told me sometimes he will put the spring back in the lifter sometimes no. I believe mine have nothing in them No spacers shims etc. I have a few sets of lifters I will try and take some apart and get some pics to share.
Not sure on my compression but cranking compression is 240 PSI
Rick.... you have 240 cranking pressure and you run
PUMP GAS... I would never have thought that... I know
the timing is a lot less with the gen 3 but damn thats
a lot of cranking pressure.... sure opens my mind up
on this engine

Awesome Ray! I bit the bullet and am going with Mean Street 6.1's for now. My cam and piston combo made Apaches too much of a roll of the dice. I think my 8 3/4 will thank me later anyway....
Mopar to the bone!!!

What kind of changes are necessary for the 6.4 heads to work on the 5.7 bore? Just a notch of the bore? Special piston valve reliefs? Would like to jump on a set of 6.4 heads if they can be used on a 5.7 block efficiently...if they are a waste on a bore that small, or not worth the work, then I am just going to pass.

I wouldnt use these on a 5.7 block personally. How much power are you shooting for? The best head for all out turbo use IMO would be the Thitek's because of the thicker decks and better quality of material across the board. In a turbo application I think you would run out of sealing with any stock head before the Apaches would show a distinct power advantage.

However much power stock parts can handle lol...I have no interest in building a G3 hemi to only go and spend coin on Thitek heads. To me, the appeal of the hemi is how well the stock heads flow, both as cast and ported. Combine that with a good bottom end, and I can't see why 8-900hp isn't attainable.
I do want to stay 5.7 for blocks because of cost and availability....If the 6.4 head is really no good on that bore size, I will save my cash and put some work in to the stock 5.7 heads

I was replying to Mr.P. I'm not gonna tell someone to not try something without having done it myself. Will the Apache bolt on to a 5.7? Hell yes. Will you need a bore notch? I know I have read that you do. So what, for the price of these heads it is probably worth it compared to no heads at all im sure. They do need an intake that can be opened to their huge ports though. People have said the smaller heads have better velocity but at 8000rpm I bet it evens out.
Sorry, I assumed you were responding to me since there was no quote and it was right after my post....you make a good point about the Apache's though...
