388ci stroker swap

Here is my 1987 Camaro Z28 with a 350 4bolt main from a 76 camaro. Bored. 60 over, 400 crank, machined block for clearance of crank. I have big plans for this car. What do you guys think?

Re: 388ci stroker swap

My biggest concern would be the .060" overbore. Unless it was sonic checked to know if the cylinder wall thickness is okay.

A GM cylinder-block with 0.060" over cylinders???

You are far braver than myself!

You best stay away from any type of power-adder.
