really 100 hp from a cam swap and some porting?? that seems worth the cost and effort.

Really when you think about it, 462 with un-ported E-heads, Performer rpm intake and a Q’jet. Basically Ram Air IV hyd cam with 520 lift made 500 hp. So yeah a 505 which is 43 more ci, 330 cfm head vs 270-280 head. And that Road Paver hyd roller cam, better intake, yes 100 hp easily. Place your order. You want fries with that…LOL

but i have the OF hyd roller and 505 now. can porting and road paver add 100 hp to what i have?

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.

Quick question for you, whats your compression? And whats your can specs duration and lift. Don’t remember them if they were posted

[Gach]

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.

Just don’t want to give you false hope on 100 hp.
