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.

Got it idling decent finally.
I got an accel advance kit thet has a very light spring, 10 deg. advance at 900 rpms. The car likes 18 deg at idle. This worked out well, set the initial at 8 deg BTDC for easy starting when hot, when idling at 900 RPMS I am at 18 BTDC for the smoother idle. This adds up to 32 deg total advance, plus additional vacuum advance if I need it, which I can adjust quickly.
The new 302 is dangerous now, I got into it a bit yesterday, I hope I don't break anything. I am hoping the CVs will act as a "fuse" to protect my tranny, which I already have a decent amount of money into.
Now I have some surging bet 1700-2200 RMP at light throttle, I think I am going to richen the mixture up a bit, that should help.
Thanks for all your help

part thottle surging is a pain, you can kinda fool it by playing with the fuel pressure. you hav a regulator right? go up or down a pound and see how part throttle reacts. you might work out with that and just readjust the idle mixture.
