I believe its a secret myself, because I have done several searches (I have a 92 350) and have never gotten the same output.

But anyways, what I do get is this:

190 hp 300 lbs-tq
200 hp 300 lbs-tq
200 hp 310 lbs-tq
210 hp 300 lbs-tq
210 hp 315 lbs-tq

So just pick which one you like I guess.

If I were just guessing the ratings judging from my truck's performance, I'd guess something like 230 hp and 325 lbs-tq. But that combo never shows up. (my reasoning for the 230 hp is it feels AS strong as a vortec, but not quiet as much power, and as for the 325 lbs-tq, again, it will run fender for fender with a Vortec 350 untill about 85 mph, and they had 335 lbs-tq I believe, so I figure mine has to have close to that)
Thats just my truck, my cousin has one just like it except for extended cab and his won't run like mine.

Ok, that is one set of specs I have found as well. That makes since too I guess, especially on the tq because they fill as strong in low rpms as the 4800/5300 engines.
