I have 2 sets of stock 19 lbs/hr injectors but they are both high millage. Found a deal for some low millage (15K) Ford Racing injectors for $70 They part number is f1ze-c2a but I can't find any reference to them. They also have 267 stamped on them but the person says that is not the part #.
He had them on a 93 LX. He bought them from www.50resto.com

Are these going to work on a 305 TPI and will I be fine without tinkering with the PROM?

 

Those look like the same ones I put into a Cadillac 4.9 my wife has.

They work fine in that. I'd expect they'd work in a 305 too.
