Yikes - looks like mostly bad news here! Welcome to Club Hot Rod, eh?

Well. to add injury to insult, I concur with the above. As Jerry mentioned - do not force the lifter out the top - I've seen some nasty scoring and even broken lifter bores from applying too much force to "pull" the lifter out. As Gary mentioned, all that cam material has gone somewhere throughout the engine. It would be best at this point to pull the engine and do a complete tear down and plan for a rebuild. This will give you a fresh start and peace of mind that everything inside is new.

That said, let us know what you're working on (1964 Chev? Just a guess!) and you'll find the world's greatest bunch of guys and gals here with a lot of years of motor-building-know-how. We'd be pleased to offer advice and suggestions on a rebuild from stock to wild. Jerry's been building for a long time and Pat McCarthy is like "World Famous" for his engine building skills. The rest of us chime in with a lot of our own experiences. Lot's of small block Chevy folks here.

Regards,
Glenn
