A little history about me, I have rebuilt Fords, Chevys etc off and on since I was 15. Last year I caught the Mopar bug and bought a winter project a 1974 Dodge Dart for me and my son to work on. I had my local machine shop dip/clean and inspect the 360 block as well as bore it .030 over, install cam bearings and deck the block.

I have installed a
SCAT 1-98112BI Series 9000 Cast Pro Comp Lightweight Stroker Street-strip rotating assembly
with 4" stroke, forged flat top pistons, rod length of 6.123. 408 Cubic Inch
Edelbrock RPM heads 60779-with 63cc combustion chamber 2.020 intake valve 1.6 exhaust valve
​Max lift 0.575
Comp cams pro magnum adjustable roller rockers 1.5 ratio

Comp cam CL20-602-4 Hydraulic w/ .507 intake lift. .494 ex lift - 291 intake/ 312 exhaust duration H

I get the pushrods adjusted and when I rotate the engine, it bends the push rods.
I assume the valves are hitting the piston but they shouldn't be. The pushrods are stock, could they be too weak. I am removing the head tonight to check if its actually hitting but have been giving myself a headache thinking the cam has too much lift etc.

Any help to easy my brain is appreciated
