What year is the 351? I know they went to a one piece rear seal in 83 but I think the 50 in oz weight didn't come till the late 80's or early 90's. I know it was still 28 oz in 83. If so, you can still use the 302 flywheel but not the pan. Sorry. Also, the Hedman headers are pretty good but the back bolt to number 7 and front bolt to number 8 are really hard to get too. Do yourself a favor and get either allen or 12 point bolt!!! I have the 5/16" stainless ARP and I wish I went with those.
