Anyone know combustion chamber sizes for eagle and apache?

Wondering what the compression would be for putting an eagle on a 6.4?

Maybe I'll start a new thread for this, what do you think?

Approx new prices for a NEW high comp (12/1 or better?) G3:

3500--OEM 6.4 shortblock,has steel crank
1500--OOTB eagle heads, change springs if needed
0720--ritter intake
1100--Dominator carb
0720--MSD-6 & harness
0700--dragpak type cam, suit to fit combo or use 6.4 cam
0420--lifters
8660--total

Add a few other new parts and maybe pickup other pieces used and have a NEW high comp motor for around 12K or less?

Get a used low mile 6.4 shortblock and it gets even better...

We know the rods and pistons are OEM, but these motors have proven to be strong and take lots of abuse. As much as I don't like the VVT configuration, people are locking this out and making big power reliably.

If you figure a moderate, but realistic 1.5 HP per cube, we get 588 HP for this 392 build. Go with 1.54 HP/cube and get 603 HP.

This seems like a lot of performance for an essentially "bolt-together" motor that wouldn't need a lot of support (if any) from a machine shop. Of course it would be advisable to measure and check/adjust everything as necessary.

Just a thought, as this is what we have readily available and to use with mostly new OEM pieces.
