Estimated Numbers Hey guys im getting ready to undergo my first head cam swap and i was hoping i could get some estimates on what the numbers might be.
BTR stage IV cam 235/242 .621"/.592" 111+3
Stock 243's
Hardend 7.400 pushrods
GM MLS gaskets
(was also hoping someone could help me calculate the compression)
LS6 Intake
FTP 98mm LID
TSP 1 7/8 Headers
X pipe with full exhaust
3600 stall
All supporting components
Car last dynoed made 342 with just full exhaust.
i know dynos are just a tool but i would like to know what it should come in at just in case it seems low
Thanks Walker

Summit racing has a good compression calculator. (Sorry if breaking rules as non sponser)
Bore size = 3.893
Stroke = 3.622
Chamber Volume = 64cc
Most ls1 pistons are .006" out of the hole.
Which equal -1cc
Deck will be calculated as 0
MLS gasket =.051" they may compress to .049"

Consider adding lifters to your build list. Much easier while it's already apart. Especially consider lifters with link bars. There's another thread on here where an entire engine was lost from a lifter failure.

No will be perfectly fine .
Don't forget Injectors as you'll be needing them soon. Bet you hit 100% DC once this is completed.
Make sure you measure PR length. From reading on this site since joining, 99.9% of lifter/cam failures are a result of poor or lack of valve train setup knowledge.
Rather than admit fault, it appears some manufactures get drug through the mud.
By no means am I concluding you don't understand, just emphasizing the importance.
