With stock settings in each truck, the same. With maxed out pumps and the mods to support the fuel I would say 50 to 75 horses more for the non i/c 4x.012's.

Its been said that on paper non-I/Ced injectors should flow enough fuel for 400HP with a really good tune. Dont think anyone has done it but they say it can be done.

Gearjammer91 on 1stgen said he made 400 with his. Of course it had a rag. I got 297 out of mine with a stock auto.

Actually I am asking how much hp does the non IC sticks have over the later IC sticks. I understand they flow more volume so more fuel=more hp. I'm probably the only cheapo that may look for a cheap set of non IC sticks over fighting the wife and that pocket book for a new set.

Your not going to get a set of stock non i/c 9mm sticks into a later factory cooled head with the smaller 7mm holes.
