please help picking motor..

????? that sure wasn't the 360. i think your thinking about the 340. and i don't think you can punch a 318 to 340 size.




did they make a rb 383? pretty sure they are all B motors.
Yes but hard to find and I think your right about the 318 to 360. I think were confusing the guy. He only has two or three options this other guy has to sell. 273, 318 poly and 383 and yes 361 383 400 were all B's . Don't underestimate the small blocks.
