make sure an early (28 oz) flexplate. all 351w engines are 28 oz ext balance. also make sure it is the same tooth count to match to the bellhousing. what transmission? if a C6 then 164 tooth. if C4 then could be 157 or 164 tooth. if this is the flexplate off the original engine in the car, should be no problem; just use it.

stock starter should work.

check that both covers are the same thickness. there are 2 different thicknesses & will mess with your pulley alignment. ther is a 5/16 in difference.

you'll probably go crazy.
