Speedmaster vs Edelbrock air gap intakes

The Blue Print engine has the Edelbrock on it.
If the bombcycle, with the SM intake, was in a duster with DT's drive train... that 200k 5.9 would be well in the mid 12's, maybe low 12's.... so the intake must be work'n some. That is probably one of the biggest dirt road engines on this site.
