Re: Chevy 350 rebuild opinions
An earlier model flat tappet cam will fit into any Gen I 350 block, even an 86-up one-piece main seal, roller cam block. However, not all one-piece main seal blocks had roller cam, or were drilled for them.
Look at the casting number on the back of the block to see if you have a one-piece or two-piece main seal. It's on the top ledge of the bock just behind the drivers side cylinder head. On a newer one-piece block it's behind the pass side head.
Many, if not all, of the newer one-piece seal blocks had "5.7LG" cast into the drivers side, and "880" cast on each side of the block under the heads between the freeze plugs. However, there are some one-piece seal block castings (at least 1) other than the 880.
No flak on the overspray, please.
