I am porting my full intake and while doing so I got injectors for free that are out of a 5.4 1998 f150 that are supposed to be 19# inj so I was wondering if these work as a stock replacement on my 305 I know that Ford's fuel pressure is 40 which isn't a problem. But supposedly these inj are good to 304hp from factory. I have the plugs for them and everything, I just knew everyone used the 5.0 inj so I was seeing if this matched up as well. Also if anyone knew when porting the base on the tpi what not to port much as I have read the floor or roof is pretty thin.

I know someone has to know a thing or 2 on this.

 

No with your fuel pressure they will be 22lbers

Find some Bosch 3s part number 0280155771 and run double orings to get the height the same-they are 19lbers with your fuel pressure. If you can't find them message me I have them for $25 shipped.

 

Actually its actually the fuel inj company that sets # per hour not ford and it's universal 43.5 psi from the inj company. ford just runs 19# inj at 36-40 psi which is actually less. I got the inj in and the entire car running. the inj weere short height wise but putting an o ring at the bottom got them to work

Couldnt tell you on the injectors but theres plenty of material on a stocker for porting. Dont go nuts on the floor but theres ample material to pick up cfm quite a bit.
