There more than one way to build a 377 then...I know its an odd combo but using a 350 block as a base and using the 350 tpi heads opened up a little and the tpi manifold opened up a little could make a fun streetable little motor. The question still beckons, which cam? Looking for bigger than stock but not too big that its going to effect driveability and emissions testing?

not sure, you probably need to narrow down all the other variables and then select a cam. CID, heads, intake, rpm range, compression, gears, etc.

Put in a stump pulling cam and watch the ls car blow the **** by in 3rd gear.

If you do a stealth ram and a nice cam on your 305 you should get a very nice increase in power without spending over your 1500.00 budget.. Maybe even get some head work done.. If you had more to spend then I would say get a 350 and do that build but if you do a 350 build with the stock TPI intakes on it would it make more power then a H/C/I 305 with a stealth ram setup?? If I rememer that year 305 tpi vrs 350 tpi was only a 20 hp difference or so.. 245hp for the 350 and 225hp for the 305..

Small bore 305 block and the TPI intake are both gonna hurt the power. If it was me I would rather be "stuck" with TPI than "stuck" with a 305 block. At least you can port the TPI to open it up for a little more power up top, the small bore 305 is always gonna be a problem. The TPI is also easier to swap out in the future when time / money allows.
