I am hoping to exchange my JPT C4 & converter for a 5 spd.  Manual brakes.  I will be using/trying a 800, 850, or 950 carb.  Super Victor, MoW 18* 235cc heads w/64cc chambers and flat top pistons.

Intake installed at 110 w/112 LSA

The new cars, LS and Hemis run the ICL in the high 1 teens, to compensate for the high compression, and run a small cam that will pull well in the upper RPMS


If only our cars had knock sensors.

So the new combo will be as follows:

347 with 10:1cr
5.4 rods
14cc Dished pistons
4.060 head gaskets /.041 compressed
58cc AFR 185 heads
1.6 let's
1 3/4 shorties
Rpm Performer 1 intake fully ported by Panhandle Performance
2.5" exhaust with H pipe

Would you mind plugging this combo into your EA? I'm curious. Does the program suggest cam specs?

Are you really going to go through the trouble of replacing the pistons, it'll drop a point of compression for sure

Yes. I've ordered a new short block. My son is buying my current one. The engine will be going from 5.315 rods to 5.4 rods, flat tops .010 in the hole to 14cc dished at zero deck and ported TFS 170 heads at 61cc's to AFR 185's @ 58cc's. I'm open for suggestions on a cam that will provide a good dcr.

Why go from ported TW170's to AFR185's?  Its doubtful they will pick up anything over the wedges and the wedges could be milled to 58cc's as well.  Do you already own the 185's?  Unless you already own them it doesn't make sense.

I know what you are saying. I haven't had the 170's flowed and I have no idea who ported them. I'm not even sure that the heads are truly 61cc. I'm not trusting any of the local machine shops anymore.
My plan is to build a fresh engine with known products. I'm tired of second guessing everything. My current engine is going to my son.
