1965 Impala BBC Stocker Update

[Greg Reimer 7376]

I've got 3 2 bolt main 396 blocks out in my store room. I'll look at and write down the numbers and we'll ID what they are. You got me curious.Isn't there a grooved rear cam bearing available to enable the use of the later cam in the early block? I know that a 409 has a grooved rear journal on the camshaft itself.That must be where they got that from on the early 396.
