Alright guys, my 381” 360 based stroker with a stock bore 4” piston and 3.790” stroker crank had issues and is out of the car and apart… I can rebuild what I have and go 4.030 bore and 3.790” stroke for 387” but I can’t seem to find any off the shelf pistons for the 3.790 stroker crank and custom forged Pistons might be a big up charge…. I could go 4” stroker kit in either a 340 block or 360 roller block that I have with an off the shelf piston by going to a 4” stoker crank… I have ported 53cc closed chamber w2 race heads and the goal is to go 10.5:1 to 11:1 compression as well as about 540hp so it’ll need 15-20cc ish dished pistons. Current 3.790 stroker setup is on reworked stock rods and Forged stroker crank.
