Yeah put some V-Force reeds in it. You'll pick up some horsepower.

42hp You must have NOS The best I have seen on a EX was a fully loaded 465 stroker making 40hp.

well thats the most ive got. i figured 40-42 range. this dyno is mine just one compression level high with out the exhuast. and ive got the slip on. so i figured im in teh same range
