Well at one time i had a tsp cam in it with pacesetters it did 303 /313. that was with the 5.3. Never dynoed it stock but it for sure made a hell of a difference. Have not towed with it yet but you can tell the power is there now. Its at like 12-13mpg was getting 20 strait freeway when stock. usally 16 mixed.

did you have to notch the pistons for the l92's?? i noticed when i pulled the heads of off my ly5 the pistons where dish along with being notched. i 've been looking into putting these heads on my sss with a nice size cam.
