man, this thread makes me feel alot better. doing a 355 right now, and my cam guy was wanting me around 11.5 - 11.8 to 1 compression on pump gas, and my engine guy was screaming thats way to high. decided to choose a diff piston and cr should be around 10.6 : 1 now. and i was thinking that was too low. the cam i was wanting was a 236/242 on 110 lsa. 608 lift i believe. --or-- a 233/239 5xx lift 110 lsa. with that lower compression, will i have to choose a smaller cam? thats what i was told...
97 6 speed lt1, (weekend driver)
i called a few machine shops, they ALL recommended staying below 11:1 on pump gas. one even said below 10:1 lol! they are around 10.5:1 stock correct?

WOW, talk about resurrecting a thread. LMAO.

Well to give you an update. With the 72cc Pro1's and the CC 282X cam, the car runs consistent 12.2 @ 111 mph. We still to this date haven't really tried different tuning. We are going to tune and test this year and once the car stops getting faster; I'll spray it. I think we can squeeze another 2 tenths and 1 -2 mph out of the heavy car. I am also going to use a full slick instead of a drag radial which I am hoping will drop the car's 60ft into the 1.6s.

The nitrous should put the car in the 10s
