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

 

ICT Billet has a nice chart for that. They even show measurements incase you are still unsure about your application.
