Other than changing the harmonic balance or is there anything else that you guys recommend I do?
400 block. 383 steel forged crank. Milled .050 Off the deck. Bored the cylinders .040 906 heads. Ported. custom cam grind. I hesitate whether I want to make a full roller or not. Again any recommendations please. running a 750 Holley.


Any feedback on this build is greatly appreciated

 

Just need to balance it and use the correct balancer and flywheel
