Input needed for a possible H/C/I setup Here's what I'm thinking for my '99 SS (roughly 61K miles)... I'd like some input, good or bad:
Thunder Racing TRak Cam (231/234 .640/.590 112 LSA)
PRC 220cc 5.3L Stage 2.5 CNC Ported Heads
FAST 92/90 (NW TB)
Kooks 1 7/8 Headers
My car already has Futral pushrods, ported oil pump, ls2 timing chain... so I'd probably need to get some decent lifters and headgaskets, and I'll be good to go.
Let me know what you guys think.

The PRC 5.3 stage 2.5 with 62cc chambers and a .040" thick head gasket will get you roughly 11.3 static compression and 8.7 dynamic compression (assuming +4° advance ground in). Your cam has quite a bit of overlap, with 9° at .050" lift. My opinion is that you are going a little large on the cam, but it will work fine with the proverbial "good tune".

Is this going in a daily driver car? Your cam is ground on an LSK lobe, which isn't recommended for a daily driver because of the severe loads on the valvetrain. Do a search on "LSK daily driver" for a good discussion on cam lobes.
