How do you set distubitor timing on pontiac 455?
No, they are completely different.
The Pontiac 400 has a bore of 4.12 and a stroke of 3.75. The Pontiac 455 has a bore of 4.15 and a stroke of 4.21. The 455 cylinder heads will have larger combustion chambers than the same year 400 heads to achieve comperable compression ratios on the larger engine. The blocks are physically the same size, but 455 has larger main bearings than the 400. 455=3.25 400=3.00, so crankshafts will not interchange. Cams,heads,intakes,exhaust,connecting rods,push rods,rocker arms...etc will all interchange.
No, they are not the same engine. The Oldsmobile 455 had a bore and stroke of: 4.126 X 4.25 The Pontiac 455 had a bore and stroke of: 4.152 X 4.21
Sure it will. Pontiac used the same block for all of it's 326 to 455 engines.

Can you bolt on earlier heads/intake/exhaust manifolds.. from a 1970 Pontiac 455 to this 76 455 engine.
No, Pontiac stopped 455 production in 1976. They are easy to swap in though.
