M1 Sb intake. Best for small blocks?

I disagree on that much converter and your listed 4500 rpm. I’ve run a slightly bigger cam (218@050) and the low end was OK. Not great. A stock converter can be used. A factory high stall (2500) would be better. The issue is where he will cruise at. I would not want it stalling. A loss of power and an overheating transmission is at the boarder line, IMO....
yes I disagree right back at you lol it's still going to be mushy on the bottom end. Poop or get off the pot if you're going to run that stick those gears and stock converter are just okay.
