Just as the title says. I want to find HP & torque numbers for a stock motor. Anyone know any web sites, thanks. Already searched.

Where to find stock engine HP & torque numbers?

What engine are we talking about, what year, and what vehicle?
Your engine had a 4x4 donor, but I don't believe that made any difference (?).
??? Clarify ^^^.
Did you even know the HP & torque numbers when you bought the motor? My buddy is telling me I should just go ahead and put this motor in the burb instead of the K5 and then get an LS1 motor for the K5.
What I mean is that I didn't think that the power/torque numbers in stock form were any different between 2WD and 4WD...but I've been wrong before.
If memory serves correctly that engine was around 250hp and 400lb*ft.

I was thinking the TBI 454 engines in trucks of this era were 230 HP/ 385 ft-lbs., but I did find reference that there were 454 engines in this era rated up to the 250 hp/400 ft-lb-ish range. I remember driving both 454 and Ford 460 trucks in the mid-90's (bunch of farmers and such had them) and they were never that impressive, escpecially by today's standards.
That engine is listed as having 230hp @ 3600 and 385tq @ 1600
That info is for a 93 suburban with the VIN N 454 TFI engine (TBI)
Thanks Scott. Not real impressive numbers. Decent torque I guess, which is all that really matters. 385 is easy to get out of a 383 though but at a higher RPM I would assume. Small block has to spin faster to make the same torque right? I know there is the other thread 383 or 454? this kinda goes along those same lines. Although getting more torque out of the 454 would be much easier. Would assume this 454 has a cast crank. Would running a steel crank yield more torque? Worth the money?
A forged steel crank won't make any more torque at all than a stock one - it will handle more power and torque if you built the rest of the engine to produce higher numbers.
The limitations of the TBI engines were in the head/cam designs. If you take steps to get past these, you then need more fuel and can potentially max out the capability of the TBI fuel system (simply can't flow enough for huge HP numbers).
I think people get too wrapped up in HP/torque numbers on paper...while not a monster, that engine makes very good torque and power down low and is very reliable and will last a long time.

This is EXCELLENT info right here.
Robert, there is no subsitute for cubic inches, if you want better reliability with less strain on the engine then the larger engine always wins (doesn't have to work as hard as a smaller engine to produce the same numbers). Also keep in mind that the 385 tq is basically just above an idle which is where you want it for a work horse engine or even for crawling.
