Can someone tell me where I can learn more about roller cams etc. Just to give me an idea what would a full roller setup cost for a 355?

Scoot,

At UltraDyne, roller cams run about $300, sometimes a little more(rear drives, inverted flanks, etc). Typical springs are $125, steel 10* retainers and locks are $74, pushrods about $135. there are two types of roller lifters available, the Crane-style horizontal-bar, about $255 at places like Jegs, and the vertical-bar, about $325 from me when I make some more.
You can see it will cost over $800 for a roller cam and kit, not including rocker arms, a stud girdle, or a rev-kit(not always necessary).
what do you get? Years ago we ran a dyno test involving my best solid lifter cam vrs my best roller lifter cam. They were both 288/296 at .020", both 255/263 at .050", with the roller having about .075" higher valve lift. Obviously we used the correct springs and lifters. The difference was 30 ftlbs of torque and 60 BHP. Those two cams are still two of my best sellers.
You can have lift curves with roller cams that solid lifters can not come close to, and the HP and torque go along with the lift curve.
You get what you pay for.......

I hate that saying, "You get what you pay for", but......9 times outta 10.. it's true....Scoot, Ultradyne has good stuff like alot of cam mfgrs. do. You don't need roller at this point....You need a West Plains dry slick cam....ask UD or others for their recommendation....my 2 sense...which ain't alot, but....

Thanks guys for your input. I hate to say it but I'm leaning more towards dropping to Hobby class or run pretty much what I have now in Super. I do plan on getting a new set of heads and a lighter rotating assembly and lighter clutch setup though. I just dont have the funds to do what I want to right now. The problem I have is I'll be mid pack in Super, but my car wont get beat up to bad. I should be a front runner in Hobby, but they are very very rough. The higher in points the farther back you start in the heats. Which should make me a better driver though. I'm afraid of having to do alot of work to the car during the year.
