330 harmonic balancer

[soma]

hey guys,got back to messing with my 330 im rebuilding and the balancer has signs of twisting and is pretty ballooned out in back.been reading around and i think i have my answer already but would like to know for certin that i wont be able to use the normal 455/350/307 balancer.it looks different and is i think a bit bigger circumference wise but not really having any luck finding a replacement.am i just going to have to go aftermarket?

Was your 330 originally a 4bbl or 2bbl? 4bbl engines had a larger balancer than the 2bbl engines. Check with OE p/n's for 350's & 403's since they have the same stroke.

I may have one sitting on a 330 crank, will take a look if you want.
