Good evening, I’m new to the forum. I’m building a Wrangler stroker engine using a 4.0L block, 4.0L connecting rods, and a 4.2L crankshaft. For the valvetrain, I installed a Comp Cams 68-401-5 camshaft, Comp Cams valve springs, and Scorpion 1.7 rocker arms (the standard ones, not the adjustable type).
My question is: has anyone used this same camshaft and rocker arm setup and can tell me what pushrod length I’ll need?
