What is the difference between a Pontiac 400 and a Pontiac 455?
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.
