454 crank into 402 build 550 hp goal

Building your engine with the 396 Callies crank and these Speed-Pro forged pistons will have a compression ratio of 11.372. A set of Scat I-Beam rods with L19 rod bolts should hold the pistons to the crank. The DCR will be 8.830 which means you will probably need 100 octane gas. Speed-Pro Forged Pistons ZL2242NF60 - SummitRacing.com Get the Afr heads with the 109cc combustion chamber. When assembling the heads make sure you use modeling clay and check the valve to piston clearance on each cylinder. I really like the Crower 01486 solid roller to go with this bottom end. .651/.677 lift and 260/270 duration. 107 LSA and 103 ICL. The 11.372 compression will work with this cam. Try to assembly the valvetrain with the lightest materials. The 396 and 427 engines like to rev high rpms so get the best lifters you can. Also adjustable guide plates and heavy wall hardened pushrods will be needed. A Edelbrock Super Victor intake and a Holley 1000cfm carb with annular boosters should top it off.
