Can anybody help me calculate my compression??
I will be running a 347 cubic inch LS1 block with Mahle 4cc valve relief pistons, TSP's LS6 heads(62cc) with .040 cometic gaskets, and the T2 TSP 232/234 .595/.598 112 cam

Thanks in advance
Seth

 

SCR will be 10:8:1 with around 8:2:1 DCR depending on advance. I figured using +2.

 

Hey i apreciate that

 

10.4:1

 

Wrong

 

Really!
i just used the calculator from
http://www.c5frc.com/calculators/Com...Calculator.htm

 

Try this one:

Uses the cam info; yours did not

 

That calculator does not go "above deck" on the piston height. If you enter .007" as you deck height, then you just told it to go .007" below deck, hence the reason you are .4 off from me. You have to enter a negative number, as weird as that sounds, to be above deck and that calculator does not accept negative calculations .
