I have just picked up two d16a6 blocks and a d16y8 head and am currently planning a high compression NA build
This is my first time building an engine and would love all of your input
Basically I want to run pump gas and was wondering what the highest possible compression I could run on 94 (California’s highest octane pump gas) and was thinking 10.5.1 would be where I’d draw the line how should I go about making that
I bought a ZC crank will that be enough with a decked head and thin gaskets to make 10.5.1 or should I use ZC pistons aswell
Any recommendations advice and criticism welcome please inform me

What will the compression be with A6 shortblock and pistons, Y8 head, and thin HG (.028")

That will run on pump 87 with 10% alky as long as you don't lug the motor belong 2000 rpm. on 89 pump it was fine.

If you start decking the head and change the pistons you might have to cut valve pockets for clearance.
