flexplate question
Quick question for you guys:
Will the factory '71 307 flexplate fit a '90 up one piece RMS 350? We are about to dump the new 350 into the wife's Malibu and I need to know if I should buy a new flexplate. The 71 flexplate is practically new so I's like to run it again.

Re: flexplate question
no , the 86 and later one piece motors have a different crank flange. you need to use the 168 tooth flexplate and matching starter from the later 350 .
