I think I said use the E curve once or twice. It's the quickest curve, you need more timing in the 1500-2500 range when you use a bigger cam. The C curve is slow because B18B & B20B's have too much compression for the fuel available in most countries. A good one runs on endlessly until you stall it.

The 123 looks high quality, but the price makes it very poor bang for the buck, considering a good stock distributor works fine up to 8000rpm. You could have bought something useful like a 45DCOE with that money.
