First I have a 92 Camaro B4C with a 355 TPI, world class T5 , it has 081 heads on it now and I have a set of 416s laying around that I ported and polished, with 1.94 in/ 1.5 ex, milled .010, and am looking for a cam to install with my engine rebuild due too a bad piston slap from when I bought it a month ago from the previous owner. should i increase the combustion chamber size after cc' ing the heads to lower the compression a little, possibly get the 350 head gasket and check to see where i have extra room to enlarge the comb chamber?
main thing is Im worried about valve clearance, how much lift can i have without worrying about the valves getting blasted by a piston. Also with my high compression what type of duration should I look for, ive read 112 LSA is best for the TPI
I plan to port the intake, runners and plenum, it alreay has a K&N intake, airfoil, gutted air boxes, headers with dual cats through single muffler, and plan to install a 3.73 posi i have, also plan on getting full MSD setup... also have adj. fuel press reg
but for right now what type of duration and lift numbers should I be looking at for a cam, do you consider this mildly modified like i read for cam selection charts that say "for mildly modified engines" or should I be looking for more than mildly modified cams

thanks for any help

You have to look for a cam that have "computer controlled" in the description. Lunaty has an EFI section .. that's good too.

well i just bought this one off of ebay

int= .479 Exh.=.501 with 1.5 roller rockers

Dur.= 222 232 @ .050

LSA 114

what do you think?

Look inside here. You can't go wrong here. You will find plenty of choises and the best cam for your needs.

 

ok i just got done cc'ing my heads (416's) and found them to average 65cc, they were milled .010 i ported and polished them, installed 1.94 intakes and unshrouded the comb chambers
does 65cc sound right? i had a mL dropper and had to convert it to cc and found out that mL are pretty close to cc's so that was a waste, am i right about 65mL equaling 65 cc?
what type of compression ratio will i have with a 355 and and 65 cc combustion chambers?
and from the previous question do i need to worry about max valve lift since i have a hydraulic roller setup?

thanks
