Piston and cam choice for 455 build - Done! Now with parts list Rebuilding the engine for my '73 Riv. Looking for good power and streetability. I'll be putting '71 heads on a '74 block and expect the bores to get opened up. The heads and deck may get surfaced and brought true but I won't be cutting them to increase compression. I would like to boost the CR using higher CR pistons. Looking for use a stock '71 intake with a classic Quardrajet. Might go Performer on the intake. I'm planning to keep the valve train stock with hydraulic lifters and stock springs. Doing a full rebuild otherwise. Crank is back with 0.010 off rods and mains. I'm wondering about the piston and cam combination. I'm leaning towards Speed Pro H392NCP hyper pistons and a TA C113 (.472/.476) or TA 284-88H cam (.459/.470). Maybe the TA 1607 cast pistons in 10:1. What do you think about these combinations? What I'm having the toughest time with is determining if the cams are too tall for the pistons. Any idea how much lift is possible with the Speed Pro or TA pistons? Thanks!
