305 vs 350 fuel rail
Is there any difference between a 90-91 305 fuel rail and the same year 350 fuel rail? I know the casting numbers are different, which is why I am asking. I need one for my 383.
On the same note, does anybody make aftermarket rails that work w/ the LTR setup? Thank you

I cant see how the part numbers are different. The only difference would be 85-88 and 89-92, because of the cold start injector in 85-88.
The ONLY difference between a 305 TPI system and a 350 TPI system of the same year, is the injector size, 19lbs for a 305 and 22lbs for a 350.

That's what I figured. Accourding to some older posts, 305s fuel rails had different casting numbers than the 350s, which actually had 2 different numbers for 90-91.....which you would think would be 89-92. But I can't see a difference either. Thank you for the help
