With my stock 01 Ls1 Im going with a tsp 383 rotating assembly.

Im going to be boosting with sts t67 fmic

What is the right dish to pick for a good compression ratio combo for the sts.

I was told -11cc?? Will that put me at 9.0:1

Or do I need to run -15cc.

right now car is stock with stock heads... Having machine shop do the 383 just want compression right for boost.. They originally said go with -15cc dished, but are now saying -11cc dished after reviewing the estimate just want to double check

Without all the specs of the parts being used it would be really hard to tell you your compression. Looks like the shop building the engine has it figured out.
