According to the engine rules, there are going to be some serious engines youre running against.
If you want to use the parts you have, I would use the 350 block and build a 13-1+ compression 3-9/16 stroker with your heads and camshaft and save your money until you can build a nice piece.
To be competitive, I think you would need a lot more engine. With the exception of the dry sump oiling, the engine rules are the same for the latemodels.
