Well from what I can find it says that the cobra block uses a 3cc piston stock? If this is true the compression ratio would be about 11.9.

Ok this might help with your calcs.
Heres the specs on my heads:
46cc combustion chambers; 180cc intake runners and 67cc exhaust runners; 1.78" intake/1.45" exhaust valves

I dont have my cam specs with me right now but they're VT stage 2 N/A's

Mine was 10.5:1

I know all the other measurements I need to know I'm just not positive that the dish is 3cc. If it is then that should be correct.

10.1:5 on a blower app. Good lord man. lol. Whats your name by the way jake if you dont mind me asking. Or i guess i can keep calling you lizzy. lol

Fred!
I ran the setup for about 8 months(10.5:1 compression and 8psi boost), but I installed the meth injection so I could crank up the timing!

Ok good deal Fred. Always nice to chat with a fellow FF. Especially since all my friends here in CO springs are military haha and im the only guy thats not. Yeah man that meth does it. I am looking at putting the N/A kit on my system so i can bump the sh*t out of the timing. I've gone in and talked to Matt Snow a few times. Haha went on a three car t/a with roll over today infront of Snow Performance lol. Nothing blew up though so that sucked but good news is there were only minor injurys

It's cool because now when everyone says I" don't want to do a pi swap because I want to s/c later" there is prove that it doesn't matter.

lizzyfan

We call that a PI 10-10 in these neck of the woods!
It's cool you live that close to Snow Performance! They have some really good techs that helped me through the install! Alot folks are unsure/afraid of meth injection but I'm sold on it! I'm running it on the new setup as well and my tuner was able to really up the timing!

Yeah dude i can throw a rock from my appartment and hit snow. The only thing between my place and his is safeway lol. Yeah man all my buddies have snow kits on their s/c cars. Its huge up here. Everyone has it. Thats why im so surprised that no one has it around here
