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!! :D

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

Clean truck man! I would drive one of those any day

On the spray you start at 12-1 then it goes down to 10-1 afr?
Am I reading that right?
How do u control timing, tune and fuel for the spray?

Any underhood shots?

I need to jet the fuel solenoid down a touch to lean it a bit. I didnt carry my jets with me and couldnt change it. I hope it brings the power up a bit when i lean it a lil bit on the spray.

Timing is controlled and pulled via the timing retard on my msd digital 6 box.

i need to take sum better pics but heres a couple that were in the dark...

.....and yes i had to keep my ice cold ac :D

I would love to see that thing on a track

Sweet truck ! Looks great under the hood , glad you kept the serpentine setup,


Some polished wheels would really make that truck pop .

That think is a torque monster. Gotta say the early and mid 90s was my favourite body style for gm boxy yet sexy

ive looked at so many wheel styles lately that ive bout confused myself on what would look "just right"..haha

the black wheels are 17x8 front with 235-55-17 and the rears are 17x9 with 325-45-17 m&h drag radials

heres a pic of it on the stock wheels and before i tore it apart an give it a paint job. i had the stock rears widened to 8.5" wide and run 315-60-15 drag radials and i run 235-75-15 tires on the front. i had to run a 1/4" spacer and lightly trim the leaf springs to clear the 315's and keep them under the bedside lip and not rub!! i think i like the look of my stock chrome wheels better than the black 17" wheels to be honest....

Love it the black wheels. Always loved those trucks. Nice motor. 450+ ft-lbs from about 2750 rpm on the motor. Nice tow motor!!!

thanks for the good words guys!!

Man, I love that truck!

I'd love just to have a single cab of one of those body styles and drop a turbo'd 5.3 in it. LOL.


(note, I'm not saying that I would butcher a 454SS, that thing is puuuuurty).

Look again...he's now running a turbo 4.8!!!

:burnout:
