well from what i understand a stock vortec from a tahoe gt in 97 made 255hp and 335tq according to gm fatcory specs and thats with the crap throttle body stuff and from what iv read swapping to a carb adds some power and as far as the cam idk anything other than apparently its an lt4 hot cam. the compression of the engine is 10:5.1 from what the specs say. and i think the reason for the big carb is that it does have a plate nitrous system hooked up to it just missing the bottle.
