360 stroker questions

The VERY first thing I would do is have the block sonic tested to make sure you can bore it to whatever pistons you choose. I have 2 71 cast 360 blocks, one is over bored .070 and the other is .030, going to .070 to built a 416. I have all of the parts and pieces from a Hensley Motor Sports engine, including the 4" stroker crank, 3 sets of aluminum rods and aftermarket 12.0 to 1 pistons. The new engine will have a roller cam and valve train. Just keep in mind that my application is "Race only" and the dyno sheets from Hensley had it at 623 hp @ 6400 RPM and 537 tq at 5100 RPM.
