Tappet block – left (standard)
Left-side standard tappet block for the cylinder block/pistons/crankshaft assembly, listed for 1973.
71-3212 is the left-side tappet block, listed as the standard version, from the cylinder block/pistons/crankshaft section of the parts book. It's the guide that the tappets ride in on the left side of the engine, keeping them aligned as they follow the camshaft and pass motion up to the pushrods.

The catalog ties this one to 1973 in our records, and it only shows up once in that listing, so we don't have a lot of cross-referencing detail to lean on beyond what's here. If you're matching this against what's already in your engine, bring the old part or your engine numbers so we can confirm you've got the left-side, standard block and not a right-side or oversize version.
As with any tappet block, wear here shows up as noise or looseness in the valve gear, so it's worth a look if you're already in the engine for other work.
Sorry if we got something wrong here. If you think this information isn't correct, .
