1976 Buick 455
Back Home Up Next

 

I bought this engine disassembled as part of a lot of various parts. In addition to this engine, it included a 1975 Buick 455.

The engine has casting number 1241735, which decodes as a 1972-1975(6?) 455. The block stamping is simply "027" which should be the Julian date code for when the engine was built. There was no separate engine code stamped into the block, which is what leads me to believe it was a 1976 production engine - the 1976 455 engines were pretty rare units and I can't find any data on the stampings on them. Plus, 027 is a really early date - January 27th, indicating this could have been produced in early 1976. The heads are casting #1246322, which decodes to a 1975-1976 455. The drivers side exhaust manifold came with a separate heat riser valve and is casting #B-1246671-2, which isn't listed anywhere definitive for decoding, but one page I found indicates it may be a 1975/1976 unit. The passenger's side exhaust manifold is casting # B-1238094, which was used on almost every 1967-1976 Buick 400, 430, and 455 engine except for some 1968 400 and 430 engines. The engine was disassembled into it's major pieces but not yet cleaned. A crank, harmonic balancer, oil pan, oil pickup, front cover, valve covers, HEI distributor, flexplate, crank + water pump pulleys, motor mounts, and various other small parts were included. I need to sort through all of them and assemble the engine on a stand to see what I actually have and what else would be needed to make this engine a complete and running.

Here's the engine pieces loosely assembled on a stand for storage/safekeeping and hosed down the internals with WD-40 to help keep any (more) flash rust at bay.
