the 254 cam is pretty big and would be a decent cam to take advantage of the larger heads. the heads make a big part of a cam selection. list what other heads you like and get some more suggestions. this cam would be way to large for stockers or sr torquers. most of the 200cc heads have rather large valve springs that may be to much.
if you wanted a decent motor on the cheap you could go with patroit performance vortecs. the 246 cam,performer rpm,750 and have acheap street motor

I'm a fan of the old Double Hump heads, but only 2.02's that are worth hanging onto. I happen to have two sets of originals off of 68 and 69 DZ motors. Nice heads, but even the best of them won't match aluminum's. The Darts will clearly make more power and are the way to go in that regard, but the cost will set you way back. On the positive, they will be three angle valves, stainless, and with hardened seat for unleaded gas. You can also run a full point higher on compression with the same octane just by running aluminum heads. Good luck

i have a set of ported 461's ill sell you hehe.

im am almost done building a vortec 355 block with 10:1 pistons, Brodix IK180cc heads, voodoo roller 535/550 lift 231/239 duration 110/106 thats going in my chevelle very soon.

for a 327, i wouldnt go above 190cc. infact, get a set of 180cc heads, and you will be much happier.

I'm thinking about just using my intake and TPI off my original 305 and putting it on the 327, and modifing the computer to pump more fuel. Will this work?? Any sugestions??

It would choke the engine. 305 TPI intakes have even smaller runners than the 350 TPI intake, it would be a cork holding back your HP.

But would it a hell of alot faster and more hp than the stock 305?
