flexplate?

i did a swap froma 84 305 ho to a early 70s 350 well it has a bad vibration,first off i used flexplat from 305 and put it on the 350 i didnt know or realise the weight thing but i have the flexplate originally off the 350 and yes it has weights on it ,so is this whats causing my vibration? before i pull trans out again? the flexplate from the 305 has no weights but is conserderably smaller in diameter then 350 one

also will the 305 starter work with the 350 flexplat? it being a diff diameter?

Re: flexplate?

Yes you need to run a 350 flexplate. Also, you will need a 153 tooth.
Summit has these.
