hey i have a 1990 mustang 5.0 and i heard a throttle body from a 87 bronco helps alot on other 5.0s. i was just wondering if it is any better or if i should just buy a aftermarket one.

 

ive never ever heard that. aftermarket is generally always better

 

I doubt it would be any better than the stock 58mm

 

The BBK ones are pretty good.

 

my bbk sticks and I've heard a lot of them whistle, don't know if it would be my first choice again.

I doubt that when you build a motor the bronco tb would be big enough, and if its not going onto a built or f.i. motor i would spend money else where first
