so if i just go with buying a flywheel and harmonic balancer i should go with what size flywheel and balancer

well if you'd answer the questions people pose to you than you'd get an answer...like what crank= part number cause we need to know what crank balance is set to = nuetral or 28?? provide a scat part number and you'll get your answer

dude, you can pretty much bank on having toasted bearings...did u drain the oil and check the filter yet?

331 takes a 28oz or neautral balance, btw if you have a eagle 331 crank, not forged, it can not be neutral balanced, only 28oz external.

if 28oz balance was used (which is cheaper to do, not as good though) a 28oz harmonic balancer and 28oz flexplate is needed and then the shop needs thos to items plus the crank, pistons, and rods to weigh them all and spin them up to balance it, they all work together so they need it all.
