HP and torque for a 7.4

[DEERE3594]

What is the factory horsepower and torque ratings for a TBI 7.4?

 

[496 BB]

If its the 7400 Vortec (L29) its 290 HP and 410 TQ. They are very hard workers and last awhile as I have not heard of many probs at all. They arent fast motors but they can pull.

The TBI is no where near the Vortec motors in terms of power.

I think they're around 220 h.p. in stock trim. I think tq is around 330.

we had a 7.4l suburban....and traded it in the for the vortec 6.0....6.0 smoked that 7.4

Nicks right on the TBI. Think they are 210 HP and TQ is crazy low. Kinda sucked saying you had a 454 SS truck with no balls.

I had a 97 dually with the Vortec 7.4 SMPFI.
280hp and IIRC right near 400tq.

Bought it used in 2001 with 22k on the clock from some old fart that used it to drag his 5'er from CT to FL (not many times I might add).

ECLB, 4L80E and 4.10's, vinyl floor, crank windows, no power nothing. It was a beast and would pull your house down. Damn I kick myself for selling that thing, even if it wouldn't brush the sunny side of 11 mpg.

 

[M123KT-450]

Well i don't much care about MPG's. . . I am looking to swap a 454 into a truck with 6.5-T.

I need a truck that starts and runs not a loser breaker POS that requires being fixed every other month. . .

I want to turn the key and drive. . .

Stop looking for the bad in every thing. We get the point... you're not happy with your current set up.

I wasn't making any sort of complaint about the fuel mileage just for the record.
