Default 5.3 Fuel Injector swap?

Whats the best Injector for the 5.3 in a suburban? Here's the build.
5.3 04 Z06 cam 551 lift with the matching springs. 76mm 4L80E. In a 94 Suburban. What factory Injector will work without Modifying fuel rail.

You need to use a 48 mm tall injector. We have them available in all sizes from 42 to 95 lb. you will need a wire adapter for the plug also but the injector will be a direct fit

likely you will need 70LB+ injectors somewhere in the range of 70~80 LB at MAX. on my 5.7 i had 79LB injectors and made 650 , 680tq at 70% duty cycle

Only the ls2 injector will fit with a different o ring on the bottom. The ls3 is shorter. Both have us car plugs so you need wire adapters. The ls2 is a 34 lb at 58 and the ls3 is 42@58. You need 70
