I don't think it's the crank. I think it's something electrical that's throwing the engine off making it vibrate

Are you getting spark to all cylinders? Do you have access to a data logger of any kind? Pull the belt and grab ahold of your crank pulley and try moving it side to side/ back and forth. I had a SBC 350 that the crank broke on and the ******* car still ran. I mean I raced with it a few times. Dam thing broke at an angle across one of the mains, weird ****.

getting spark to all cylinders i checked that im gonna data log it this weekend. well i had a extra set of pushrods so i went ahead and changed them the heads were pretty clean it amazed me. still vibrates though. i was looking at my harmonic balancer a minute ago the one i replaced already underneath the car and it looks a lil wobbley from the top it looks good to go but from below it doesnt look so hot. if u look at the back of the pulley with the car on and watch the crankshaft u can see it running out. i never looked at the old one so iono if its gonna have some wobble. i tightened the hell out of the balancer too torqued it down
