Your B&M was probably a Holeshot or Super Holeshot. I put a Holeshot in my 69 Roadrunner and didn't notice much difference over stock. Off topic but converters have come a long ways.
Yes, it was a B & M holeshot and really didn’t stall any higher than a stock replacement converter. I ended up building another 340 years later with the 284 purple shaft and switched over to a Fairbanks converter. Much higher flash stall but very sloppy on the street.
