I was pretty sure that my truck has 275Hp but maybe that is just to the crank. I have a 1990 EFI

 

Wow, so thats what 220 at the wheels? Is that stock? And i have the TBI i thinks, but it says EFI on it too? Same deal?

 

That is certainly not stock. Stock is 210hp adn 300 ft lbs. The 454ss stock numbers is 255hp and 415 or 435ft lbs of torque depending on the year.

 

TBI is EFI(Electronic Fuel Injection).

 

Well my truck is'nt stock but its not modded too much, maybe I don't have as much power as I had thought.

 

OK so thats 210 at the motor? or at the wheels? Because if it has 210 at the motor, that means I am only putting down about 160, that would really suck

 

Yep...210 at the fly. Most dyno between 150-160 rwhp. TBI engines are torque engines.

I got my 350TBI engine down to about a 16.0 with nothing internal done by the G-tech and a 7.5 0-60, that was with headers, high-flow cat, cat back(edlebrock), Jacob's ignition system, Ultra Coil, K&N open 14x4 assembly, some TBI mods, electric fans, 3.73 gears, and shift kit/servo in the tranny....that was with about 200k on the engine. Then I dropped in my 383 TBI and went 6.7 0-60, and 15.5 1/4. I had a really small cam in it b/c I wanted a mpg cruiser b/c I was on my way to college. After 60mph, the truck just fell over.
