Hello, my name is Jr. I am currently rebuilding my stock 302 engine from my Foxbody, I'm going with cam B303- and Forged pistons, I watched a couple videos on YouTube on how Ryan builds a 347 stroker. I was wondering if I could go with the same torque specs for my stock 302 that he used for his 347?
