Lets say your heads flow 270-280 and you port them out to 330 cfm. A 30 cfm increase in head flow will make a 10% increase in horsepower, you’ll see 50 cfm increase. I think from what I’ve read your at 500 hp. The Road Paver cam definitely has more duration and lift that will take advantage of the increase in cfm. Going to a better ported intake means you won’t see as much of a drop in cfm. I’ll have to go back and read the whole thing again to give you a definitive answer on weather it’ll actually be a 100 hp increase. But just figuring using 10% factor, you’ll definitely be at minimum of 60-70 hp increase.
