LS6 with Milled 317's
 

I helped a buddy build an engine for his 00' Camaro Z28. Here are some specs:
LS6 short block
Flycut the pistons
Comp Custom grind 238/244 586/596 114lsa
cometic .040 head gaskets
ported polished 317's milled .060",
Professional products 96mm intake and
fast 92mm tb
asp underdrive pulley
1-3/4 pacesetter headers
3" true duals through raceline bullets
stock maf
blackwing air lid
k&n ait filter
ford redtop injectors
racetronix pump and hot-wire kit
Stage 2 Tdp t56
4.10 gears
26" m/t et drags


Car was pulled up to 6300 rpm's and made 464 rwhp. After that power seemed to start dropping and we figured out it had some valve float. We are switching over to a shorter pushrod and see what it does. Also Maf was acting funny so also replacing it. We think the motor has a little more left in it we just have to fix the little issues. We are very happy with the results.

those are good numbers. whats the compression ratio?

The heads were actually opened to 73cc for a previous turbo build. After the .060 mill they were are at 63cc. With the cometic .040 gaskets we should be around 11.2-11.3 compression.

How much do you think you have in that total with all the work done?
