Hey guys looking for some input so lastyear I built a 5.7 350 for my 97 used icon forged flattop pistons, stock connecting rods, stock crank, a cam from comp woth .488 .495 lift cam and shorty headers, and had it tuned by black bear and for some odd reason it just dont run right. Like itll make all the noise you want it too but if your beating on it, it goes absolutely nowhere fast and im to the point of 0411 swapping it if I can't get it figured out anyone got any input or things to try??
