Purchased a rebuilt engine for my '71 Grande. The engine has been sitting in a warehouse for five years still wrapped in plastic from the machine shop that did the rebuild. It had valve covers, intake manifold and oil pan attached for protection. Otherwise it is what you would call a long block. There is minor surface rust on the intake/exhaust and small areas on the block which has been primered. All visible internal components are soaked in machine oil. There are new pistons (more later), timing chain, oil pump, freeze plugs, cam and lifters. The heads are matching with four dot markings and the block number is D0AE-L, date code 1A19.
The pistons read H555CP, which is consistent with flat top Cleveland pistons, plus 201-01-14-.030. It has a mild cam and the heads are closed chamber.
What I like best about this engine, besides the fact I got it for a song, is the attached tag explaining the break-in process. Nice touch.
