It's a 273 now but what would I need besides complete 360 engine from a car or truck?

I didn't read all replies but I put an '88 5th Avenue swirl port 318 in my '66 Valiant a year ago and here is what I ran into(may or may not apply to what you are doing). 1. 5th ave oil pan had to be massaged pretty heavily with bfh on driver's side to allow full left turn without steering linkage hitting oil pan. 2. had to add onto 273 pass. side engine mount to work on 318(otherwise the mount would only be attached to the block with 2 bolts)I can't believe that they changed the passenger's side block lugs from a '66 273 to an '88 318 but they did . C. Air injection port area of '302 casting swirl port head had to be ground on entensively at #7 cyl to clear stock 273 exhaust manifold. IV. used an sb overdrive bellhousing/130 tooth flywheel combo. Fits good but long clutch fork force you to get very creative with exhaust routing on the driver's side. I ran the pipe between the torsion bar and the frame rail. A better was would have to been to do whatever it took to use a short clutch fork with this bellhousing or shorten the long fork.
