SBC 302 is in, running!, Needs some tuning, any suggestions? Options

[marks914]

Got the 305 out and put the 302 in, runs pretty well.
I am running an edelbrock 600,
Hydraulic roller cam .56 lift 236/236 duration.

I am in the process of tuning it right now. I have HEI vacuum advance hooked up to the timed port on the carb.

The engine has some lope to it, when I advance the distributor to smooth out the idle, it purrs like a kitten and no spark knock. The problem is when I advance the ignition timing this far, it is difficult for the starter to turn over the engine.

Here is what I am going to try, please tell me if this makes sense:
I was going to put the vacuum advance on the manifold vacuum port, thus giving more advance at idle, I do not think this would affect the initial start up advance, making the starter able to turn the motor over when hot.

here are some pics

Thanks

PS, the car is a bit quicker now, the power comes on at 3000 RPMs, so it is very driveable around town with the power where it needs to be.
