you know you can use a calculator based off +12.00cc pistons and the block hasn’t need decked. It’s going to depend on your head gasket compressed thickness and head cc.

Yes, as Tuned stated. And of course as seen in the pics, the block was not decked, just bored .030 and clearanced for the stroke. The cam is a Howard’s version of the hot cam. Can’t find the cam card at the moment.
