Years ago we had limited springs and times change with more testing.
Now,For a 24x/25x Cam static compression should be .5-1 point higher. Too me it looks like you picked a long duration cam and advanced the valve event's.This works for midrange but kills topend as you found out.If you stay with the low comp. of 9.9-1 you need to keep DCR. We went over this many times before. I garrenty a generic Cam of a XER238/248 on 115 duration install straight up would make more power than you have now and rev out.(unless the blower chokes or the intake does)I have a 427ci Vette sitting here with a D1 pushing 10lbs of boost making 845rwhp on 100% 93 octain.Peak power is at 6500rpm and holds to 7000rpm with only a 234/240XER Cam.Just think if we added meth and a bigger blower like the F1A.

I would have taken this as constructive criticism, but, in a PM minutes ago you told me quite rudely to shut the F up. You are very unprofessional so please stay off my threads.

Thanks Beaflag, we only run 26x11.5 ET Streets to help make the drivetrain live. The car has gone high 1.4 60 foots with a 347 making 725 rwhp. This 402 is making a boatload more torque so I'm hoping for low 1.4 60 foots. Wish us luck! Thanks. Dave

I would definitely recommend a cam shaft in the plus or minus 236/242 @ 114/115 range with an XE-R lobe straight up as well.... It would carry through to 7k and put down some more power..

Made 900 + with both cars. I can't wait to get to your car finished!

Thanks for the advice. We had a cam in the car a little bigger then that but pulled it for this other cam. We are going to stick old Betsy back in there and rev it out to 7000rpms. Something we need to do with our small tires is to rev it so we can make it through the traps with our tire/gear selection.

It was something that I wanted to try on a camshaft and now I know that it didn't work to my liking. Dave already had picked out a cam that was real close to the 238/248 when he built my 402 last year and I made him pull it out-not once but twice! It will be going back in tomorow-need to kill some torque!

If you can push a legit 900rwhp to 7000rpm your car should have no problem running mid 8's.

The Cam will work.I would also recommend again to slow the blower speed down too.It's good to get killer dyno #'s but sucks when you keep blowing the heads off at the track. Been there,done that -sucks.
