Looking for possible SCR and DCR calculations for custom cam My setup as of now:
TSP 5.3L stage 2.5 heads
MS3 cam 113lsa
stock HG's
Looking at doing a custom cam to help the low/mid range without sacrificing much top end.
Cam is a 233/237 on a 110, lift is around .630/.600.
Thoughts? This should clear without flycutting but im not 100% sure.
Car made 440rwhp 389rwtq with the setup above and LS6 Mani, ported LS6 TB, K&N filter with HF bridge. In addition to the cam I will be adding a Vengeance ported Fast90, ported LS2 TB, UDP, and Vararam, will be hoping to get close to the 470 range and have a lot stronger torque.
Thanks!

Stock short block?

It is a stock short block LS1 and the 5.3L heads are said to be between 62-63cc. The pistons are not flycut currently.

Get ready to flycut. That's a healthy stick and your 5.3L heads have smaller cc chambers and larger valves than stock. This hurts P to V clearance. But go ahead and plan on flycutting because the gains from the ported heads and better intake should give you a HUGE boost in power from where you are now.
