Well I just got my 6.4 heads in the mail today

http://s1265.photobucket.com/albums/jj501/540Challenger/GenIII%20Hemi%20build/

My Alum. block should be here tomorrow i will have pictures up tomorrow

---

Which block did you get . Same place as the heads?
Will be keeping an eye on you. Lol

---

The block i got through jegs. Since the block and heads are going to sit for at least a year while i gather funds to finsh the build. Since i tapped out my car fund between the hemi parts and Vet's bills

4500 cost for the block

1300 for the heads

2000 for the Vet bills b/c my 5 pound dog ate Chocolate so there goes the rotating assemble money

---

Nice had a 145 lbs rotty that ate a big green caterpillar.
Stupid thing almost died. $$$$$$$
What block did you get? I think the one that is bored to 4.114 is the better one because if the amount of rebuilds you can get.
Thx for the info.

No port volumes as of yet. Ahhhh a 6.4 deal would be very nice. I would love to work with the aluminum block too.
I'm so buried here at work who know's when I'll have time to get to the Hemi builds. I'm having some difficulty keeping up.

On a different note...I hope to be building a stroker 6.1 for my Duster by the end of the year so let's keep this going!!

---

Brian I think their is only 3 ways to make the Apache head work.
Force induction, spinning.it to the moon in small CID form or large cubes.
The second one I'm concern about possible oiling issues.
The last ,and this is my avenues, is using the 4.25 crank. Apparently BES had to sink the valve .070 to make this work.

I could be totally wrong in saying this so don't take it personal. I don't think you need any expertise to port this heads.
The port is a straight shot at the valve. No short turn to worry about.

when will we get some ported flow numbers?

A big Wedge head is a bit different than a big Hemi head! Everyone know's 426 Hemi's don't make any low speed power...it's all up top.

yes and no...you get some inherent tumble and swirl induced by the wedge head's valves proximity to the cylinder wall, as well as increased shrouding that you won't get with a hemi or pentroof (closer to what the genIII is)....but overall intke tract length, port volume, cross section, and valve timing/action I bet have a bigger influence in low speed power than valve configuration. take a similar displacement hemi and wedge, with similar port volume/cross section built similarly, I bet their power curves will track pretty closely....

here's the dyno results of Dulcich's "mild manner mauler" which is a .030 over, stock stroke 440 with 295CC indy EZ heads, comp XE275HL with 1.7 rockers, and starts out with an indy dual plane intake....

http://www.moparmusclemagazine.com/projectbuild/mopp_0510_440_engine_dyno_test/dyno_results.html

with the indy 2 plane intake, those huge heads are making peak torque at 3500 RPM, while still making 96% of peak torque from 3100 RPM to 5500 RPM, where he got into instability issues trying to run a hydraulic lifter with an XEHL cam AND 1.7 rockers...runs 3 and 4 switch to a single plane intake, and that one change moved the torque peak up to 5000 RPM, but we only see about 85% of peak torque at 3100 RPM....

here's the same motor, but a switch to a small solid roller (242@.050)

http://www.moparmusclemagazine.com/techa...no_results.html

interesting how the peak torque with the dual plane intake jumped up to basically a plateau from 4500-5500 RPM, but it's still making 90% of peak torque from 3000 RPM to 6500, and with a switch to a single plane, peak torque jumped up to ~5000 RPM, but it's only making 81% at 3000 RPM...

Well we have an aftermakert head for the 3rd gen Hemi already

Nice to see but IMO we need a cast siamese big bore block for about the same price as an R3.
Get the block and sky the limit.

Let's hope that this is just the beginning of the wave of aftermarket support this engine deserves!

---

And I also agree a block would be nice although the Aluminum MP blocks should be the way to go other than cost.

How bout this for a combo.
production 6.4 short block for 2200.
early 5.7 heads that should give you a 9.7 compression
add cam headers dragpack intake and you have over 500 hp.

OK, where are you getting a 6.4 short block cheaper than a 6.1????

Are 6.4's forged components in the bottom end? What is the cubic inch on these engines? Thats a pretty screaming deal

We picked up 30rwhp and 28rwtq from an almost bone stock 392 with only ported 6.4 heads.

6.4 is a good number for hemi's, with the apaches or nor.
