does anyone know what the compression ratio is for a LS setup with a gsr head. Or does anyone know what compression do get on piston to bring it to 12:1?

I do like how that site breaks down the variables and allows for boost.

 

Just so you know, if your using stock LS rods and want a stock piston, alot of people choose the P30 piston which requires no modification to fit the stock LS rods and will give you around 11.5-1 compression. PR3 pistons is another option and would result in .2 less compression.

 

yea, i thought of p30 with high compression valves, to get 12:1, but i rather save that money.

 

why do you need so much compression? what cams will you be running?

high compression most likely for all motor

already got the spring kit
