Ford 272 C.I. runs low 11's. Why do Mopar guys need 408's?

yo
K/G. What do you think it cost to build that. It’s not a 6000 RPM tractor engine.

EDIT: McLeod clutch (probably a soft lock) and Racer Brown cam.
u can bet there isnt anything stock in that engine , with exception of the block. My dad had one , it sucked compared to the sbc of the time , 292 werent any better !!!
