I built the crap out of my 305......400 crank etc......the biggest cam i would run would be a 270 magnum grind, reason being the small bore. you dont wat to run a cam bigger than that cause it will not be able to use it, the motor will not likely respond well with it at all. my specs are 221@.050....465" lift 108LSA..It has a wicked idle if thats what you are looking for. My heads have been fully ported and polished, torker intake and a 600 holley. Im not sure what else it has left in it without spraying it, but it makes close to 400 at the flywheel. Cam selection can make or hurt the motor and 230 @050 is way too much for the bore....unless you are running a blower i would'nt use a cam that big, it does'nt need it and it won't like it. If a lumpy idle is what you are after have a cam ground with less than 110 degrees LSA.

other mods are: 1 5/8" hooker supercomps, th400 3000 tcs stall, auburn posi, 3.73:1's 275 60 15's........lots to consider when building a motor for the street or even the track, throttle response is one of the keys. also with this cam i have to run a vacuum canister for my power brakes. the motor seems to have awesome throttle response and does not bog or stumble at all.
