The LSX376B15 comes at 9 to 1. They changed it to 9.5 to 1 when the heads were sent out to West Coast Cylinder heads.

I don't know. When I get the build packet I'll check. I think they also used a thinner head gasket than the one that came on the motor.

That can change the compression ratio. What pulley did you use?

I forget how many mills was shaved off with the head gasket and I know the heads were milled down. They have a tool to measure the all the cc's of the heads and pistons. I had a pic of them taking the measurements.
The pulley I'm running is 3.5"

When I added the meth injection and the 102mm TB on the old motor I picked up about 1.5LBS of boost just from those mods. The Whipple is set up for a TB up to 112mm. Everyone with a Whipple should run a 102mm.

you dont pick up "boost"...

if your boost # is now higher with those mods, than you have more restriction of forced air not entering your motor.
