Ok I see said 10.1 compression thats good. Also see it falls off at 5500. The Road Paver going to move you up in 6000 rpm range, thats real good its going to take advantage of that almost 50 cfm pick up. Being its a 505. To a 70-80 hp gain, and if you go with North Wind intake your going to come damn close to 600 hp.
