I am working on a 89 RS with the 305 in it.... Im trying to get the most horse power out of it and was wondering whats the best thing i can do about the throttle body...... I already have the spacer but dont know whether i can install a bigger one or install bigger injectors. Please respond i will greatly appreciate your responses.

 

Dont think changing the TB unit to larger unit will help. Same on injectors. Exhaust may be better choice.
