Im looking into several different combos for my Z-28s bottom end. Id like a stroker engine but i dont know. i see alot of guys hanging i-beams and forged pistons on the stock crank and laying down good numbers w the ms4 cam and TSP 5.3 heads which is what ive chosen to go with . I am planning on 150 hp shot at the max. maybe you guys can help me put together a good strong and reliable bottom end. what numbers am i looking at stroker 383 vs 347 ci with the heads and cam ive listed . Id like to shift at 6800 to 7000 rpms. thanks
