Goin V-8

You don't need the angle oil filter adapter. I have a V8 and don't have one.

Early 273 motor mounts, they look like this. http://www.earlyabodyforum.com/board/messages/2/456.html To mount a 360 they require a bit of modification, no big deal.

They're hard to find and expensive ($100) you'd might be better just getting the Schumacher ones.

You can go with 273 exhaust manifolds, the Durango manifolds (require some shims I've read), the 340 HP manifolds, Spitfire headers, TTI headers or old Dougs headers. Read about it all here http://www.earlyabodyforum.com/board/messages/394/418.html
