I dont have a ton of mods yet, but they are coming. Right now i have a rebuilt 355 (out of another camaro, not sure what year its from though) 2 bolt main. Freshly rebuilt, about 1.5K on it. The heads that were on it are still there, i think they are 2.02 1.60's

Or really close to that, intake:edelbrock performer,carb edelbrock performer 600cfm,K&N air filter.2200-2400 stall, th350, 3:73's

I was think about putting a comp cam extreme 274 int. in it.

It looks like it would pretty much match what i have, and still be good if i get a set of heads, new intake, and 750 carb. Would this cam perform ok with my current setup and down the line with a better carb, intake, heads? Would this cam have a lumpy idle? Thanks

 

The intake (& carb) would kill off the power above 5500 RPMs. With an RPM manifold, 750 Holley, decent flowing heads and exhaust, it will move out smartly. You might want more stall, however.
