Ugh my head hurts. I cant comprehend anything as i have a nice heqd cold. Stopped by after work. Thing runs fine, had it running around 10btdc with no knocking pinging or any of the sort on regular 87.
You guys are nutz lol
Yeah Adam, I highly doubt it's going to ping sitting there with no load. Its going to ping when its warm under load at low RPM if it's going to do it. And you still haven't told use the confirmed pistons, if they really are 18cc dish it's probably fine. And have you ever looked up the head casting numbers or cc'd the combustion chambers?
Those cam specs are at .015" lift. So that is fine with me, I prefer it, if cam timing was only given in .050" lift, there is a little mini calculator in my compression calculator page called "Intake Valve Estimator" that will convert the valve closing to advertised if you give it three pieces of info. It basically interpolates the valve closing based on teh difference between the advertised duration and the duration at .050", I think that is more accurate than simply adding 15 degrees.
So, with your BB #s in my calculator I get 9.82 static/8.17 dynamic. I would stick with premium even though you are only 9.8:1, because you cam timing is relatively small and your dynamic is over 8:1, but you should be fine.
BTW, that race gas in your Vette at the track would go real good with a 150 shot! Wake that puppy up real good!
