OK! It IS a 5 speed. I guess I'm getting old.

The block is a short deck. Casting # on the block is 140154445.

The casting # on the heads are 346236, the last 6 may be an 8. It also has GM 3T cast in them.

If their was any doubt before, I'm almost certain I have to take it down as the humidity here has caused surface rust on the cam lobes.

Here's some pics...............














Me wondering what the hell did I get myself into.
