I suggest a 72-74, 460 donor truck ,that way you'will have everything you need to do the swap.
Otherwise,It is a lengthy and sometimes costly procedure to accummulate all of the parts you'll need.
The 70-73 460's were great.
The 80's 460's I heard are Dogs.
I have a 70 429 that keeps the filling stations in business,it's pretty good engine.

'68-71 engines are higher compression (10.5:1)with positive stop rocker arms. I run 10.5 c/r on pump gas with no problems, but I use a conservative distributor advance curve and don't lug my truck in higher gears.
'72-78s are lower compression (8.0-8.5:1) with fulcrum type rocker arms. '72 up heads also have the smog bump in the exhaust chamber. 8.0-8.5 c/r makes for a real dog with the 460, as it does in any natuarally aspirated motor.
Spend the money on L&L motor mounts. They're well worth it.
