Well, dunno the type of dyno, elevation, tuned or not.. I like to hedge my bets. Lol

My 97 hawk dynoed sorta low if you ask me it had a bad opti that day , the graph looks like a polygraph it made i believe 236 hp , 265 tq on a Mustang dyno , stock hawk form .

[ScreaminRedZ]

The three LT1's I owned that I dynoed all made 230-232 stock. Those were auto's though. From what I've seen, the manuals are about 20 hp more, give or take.
