Whats the largest throttle body i can install with out doing any otherwork( intake) stock application 1992 bronco 351 . 51 mm 62 mm?all replies appreciated. thanks TR
hey you should try talking to some Mustang fans, they regularly
swap TB's to bigger sizes, I'm sure they have a whole chart to show info..... good luck
fordin K:
Good idea, except they use single throttle bodies, and most trucks have duals.
Black Ford XLT:
I noticed, while looking at edelbrock intakes, that they have two sizes of throttle bodies. 56 and 61 mm. They recomend the 56 for their truck intakes and state that the 61 mm tb requires port matching of the intake.
So I'm guessing, but not certain, that 56 mm is probably the limit.
