I have a '69 Camaro that I fully restored a few years ago and now that its getting about spring time I'm trying to get it back on the road. It was a full restoration to original condition so there's nothing high performance about it... 327, 2bbl carb, stock ignition, powerglide.

Anyway, I had the engine rebuilt and put a little throatier cam in it, but other than that its all stock. My engine builder set the timing and mixture on it (4 years ago) and I think it could use some tweaking. Can anybody suggest some specs to shoot for and maybe a basic procedure?

Ignition timing:
I think stock is 2* BTC.... is that right? Can I get more advance if using higher octane gas (89, 91)? I need to set the timing at idle speed right? With Vacuum advance disconnected? what should the timing look like at higher rpms (w/ or w/o vacuum advance).

Fuel mixture:
Do I set the mixture at idle speed or a certain rpm. If I remember right I think my engine builder made some adjustments at 2000rpm, maybe that was timing though. Start rich and then lean out until rpms drop, right? drop by how much? stay at that point or turn back some?


Sorry for the newbie questions. I tried searching for some things but most of the results I was getting seemed to be high performance tuning. I'd like to squeeze a little more out of my engine, but its not built for performance so I'd rather keep it simple and reliable. I've got a Chilton's manual to help me along a little, but I'm looking for some application specific tips. Thanks.
