What is the factory horsepower and torque ratings for a TBI 7.4? ... If its the 7400 Vortec (L29) its 290 HP and 410 TQ. Torque monster.
That’s most likely the one and yes it doesn’t lack for torque for sure and like I said, if you can make it breathe better those horsepower numbers jump up pretty quickly. Those mods are in the future :)

My grandfather had an '88 just like this but with tan interior and a snug topper (no side windows) It was white with a gold pearl and silver micro flake... shined like diamonds in the sun light.

454/400 trans/4:11 rear... you could breath on the throttle and light up all 4 tires out back.
I used to love driving that beast... pass anything on the road, except a gas station... lol

Looks like an awesome project you've got there Jacob. It will look great sitting next to that pretty Burb of yours.

Definitely subscribed...:signs1:

Burb... she’s gonna need some 20” AFs... just sayin
Definitely scoping out rims. It'll be a minute before she's ready for that step but have been looking at what AF, Fuel and Specialty Forged have to offer for dually rims :hmm:

Oh I know. That's the reason why it'll be a "minute" before she's ready for that step. The dually don't care when it gets new shoes. It's ME that's the hold up LOL The rims plus the tires is gonna be pricey for sure. I'm betting probably one of the more expensive things I do with this thing.
