1- our Hemi trucks are 2 valve right? not 4..?

2- whats the compression ratio 9.5:1? or 8.5:1?

lol downloaded me a new fangled program from comp cams and im messin around with diff set ups to see what kind of power i can get..

 

Two valve, twin plug. Don't know the compression.

 

thanks..im pretty sure its 9.5:1 kinda the standard on new motors i think pre 95 has 8.5:1 n lower i think...

 

9.6 to 1 compression
