i have a 355TPI with a mild cam and 305 heads which make about 9.75:1 compression. if i get new injectors i'll most likely get a pair of headers to go with them. do you guys think the ford 24#'s on summit would be too big even if i got my prom tuned for it??

 

The fords are good, but SLP makes 25# units for 99 dollars a set. I'd save a little money and go with them. I don't think they'll be too big if you change your injector constant, but you'll have to make sure and change it.

 

what do you mean my injector constant? and that sounds like a real nice deal, are they on summit?

 

Injector constant is just the prom tune like you said. You give the prom a value for the injector lph rating, and it makes its duty cycle decisions based on it. Make sure you change that constant tho, otherwise your engine will run pig rich. Get them from slp.
