69 383

How do I tell if I have a B or an RB 383 block?

If it's a '69 and a 383, it's a b engine.
Check the casting date on the side of the block.

RB is only, 413, 426, 440, hemi

this is correct.

The "B" blocks have a 3.375 (3 3/8") stroke.

The "RB" blocks have a 3.75 (3 3/4") stroke.

I would need to see some documentation to believe that. What year did is start and what year did it end?

My dad had a 62 Sport Fury Convertible back then with a 361. That was a "B" block and the 383 was the same. Shortly after he picked his up they offered the 383 in it. Everything interchanged on the 361 & 383 except the pistons and rings....

I could be wrong, but I need documentation to believe it.
