went for sum dyno time with the 90' 454SS
i know its not an LS truck but hang in there with me, its my fun toy!! 
my dad gave me the truck many years ago and after blowing up stock motors a few times i decided to build me a better engine and trans combo for it..... i just got done tearing the truck completely apart and painting it all over so it was time for sum numbers....so here we go!!
i took my 454ss truck an strapped it on the dyno friday to make a few motor pulls and a few nitrous pulls. the motor is a carbed 461" with aluminum heads, comp xtreme cam, roller rockers, rpm air gap intake and a 950 carb, longtubes, 3" dual exhaust with a dynomax x-flow muffler and a return style fuel system for the added nitrous which is an edelbrock plate with 175 jets in it and nos cheater solenoids. 4L80E trans with a revmax 3400 billet converter and the stock 14bolt rear. all pulls were made in 3rd gear(drive) with the converter locked. we turn the truck 6 grand but i noticed it makes it biggest power at low 5 range on motor.....
motor made 416rwhp/497rwtq
nitrous made 577rwhp/653rwtq
