seeking advice for 5.3L injectors

[shanekennedy]

have a vortec 5300 from 04 buick rainer in a 68 camaro

truck intake didn't clear hood so the shop i took it to swapped intake with a ls1

they also swapped fuel rails for holley & swapped factory 25.3lb injectors for 34.6ln from a 3.8L sc engine

i want a cruiser not a racer & would like to swap the original injectors back in

sounds like i just need to get some extensions for the injectors, but it's unclear what length

any gotchas i should watch out for or other general advice to help prevent regrettable choices ?

thank you

Just run the 34 lb injectors. They won't hurt your performance at all and it will save you some wrenching time.

thank you for the response. i don't mind the wrench time, only 4 screws.

found this over @ ls1tech
