Picking the "right" 383 block? Different styles?

ive seen mid 60's c-body 383's with the front holes tapped already. Those should be cheap and able to be found still.

I'm not one to care about matching numbers. an incorrect 383 is just as incorrect as a 400, but the 400 is cheaper, easier to find, and able to do more with it when building it.

btw, i have a whole 400/727 truck setup for sale....first $300 takes the whole thing.
