I am currently running a comp cam with 224-230 dur @50 - 535-545 lift with 1.6 rockers. I am thinking of going to a a 242-248 dur @50 with 570-592 lift using my 1.6 rockers. My question is will I see a much bigger power gainor will I hurt power. I have seen many times wre people do a cam swap and wind up loosing power. I just dont want that to happen.

here are the motor specs

355 10:1.1
fully balanced
afr 190s flow 267cfm
edelbrock performer rpm
holley 750 dp
full msd ignition
full roller motor
cam listed above
shortie headers
3in exhaust
2800 stall
ford 9in with 3.70s

I would guess that a 355 would need a top-notch exhuast system using true dual 3" pipes to take advantage of the bigger cam - but no doubt others would suggest the swap or even already run a similar hot cam.

I also think that with 3.70 gears you won't be able to fully take advantage of the peak power with the hotter cam installed unless you road race.

I wouldn't do it because it would likely lose more streetability than gain useable power but one would need to road/dyno test it before and after to be sure. You may like the results.
