I am running the KB745 step dish forged pistons at zero deck, closed chamber Edelbrock heads with .039" head gasket on a 4" crank SB stroker. Running 93 octane pump gas. Most people I talked to think 32 total is best but Ryan at Shady Dell thinks I should run 35. I have mine at 35 total now but plan to go to chassis dyno soon and try less total timing and see what happens. I definitely don't think I should be running more.
