Re: 350 GM Crate Motor questions for a 66 C10
I agree with garyd1961. Who ever you talked to doesn't know what is needed for a L31 Vortec. Yes you absolutely do need a melonized distributor gear. If you do not, you will eat up the gear on the roller cam. And yes you will need a new flexplate for the 1pc rear main seal. If the budget is an issue, why are you looking at new Edlebrock intakes? Why not look at the Summit or Jegs private label intakes. That will same you some money. The timing cover may or may not need changed. It depends on what water pump is being used. The crank sensor hole will need to be plugged with either a sensor or a metal plug made for doing so. No need for a fuel pump blockoff plate.
