I gotta buy my injectors and fuel rails pretty quick, and I need to know how big of injectors i should get...i'm running the XE276HR cam, L98 alum Heads, HSR intake, 58mm TB, Full exhaust, custom computer programming, and a few other things to bring my motor up to about 350-400 HP....i was thinking maybe just running like stock LS1 injectors because I believe they are 28#er's, am i right? i was thinking like 28 or 30 pound injectors would be sufficiant, what do you guys think? also, are all injectors the same? will i have to worry about differenent injectors not fitting with the holley fuel rails??? A guy has a set of used 36 # holley's for sale for 200-250 i believe...but 36 is too big I think..what do you guys think, how big should i go??

 

Ford motor sport 24 lbs or the SLP's 25 lb/hr would work fine.

so 36 # injectors are just wasting money then...because I know you can get new ones for under 200, i thought 250 for used injectors was kind of high...that calculator came out to be about 29#, i don't know if i did it right tho...i was told by the guy that is doing my chip that i could get away with the stock 22's if i wanted too, so i'm thinking i don't have to go much bigger than that...i'm thinking in the 25-30 # range should be sufficient....where is some good places to get injectors at a decent price, anybody know??

 

Get some ford SVO 30# from summit. Only other way to get a better price is to order from ebay or find some on forums.

 

so those fit and work fine with the stock wiring harness and holley fuel rails right??

 

I know they'll work with a stock application (TPI, LT1), not sure on the holley fuel rail. But wiring harness yes.
