From everything I have read and per the compression calculator, I should see about 10.4 compression. I might go with a larger cam in the future but for now with manifolds I'm sticking with a smaller proven cam. I want headers but haven't figured out what route I will go yet and / or which longtubes will fit. Same with the truck intake, I would like to run one but for now I have a complete ls1 with injectors rail etc.
The block got new cam bearings and some cleaning.
