Hi. I have a 1966 a series 1098cc engine that has a Swiftune cam and roller rockers. Also has a four branch sports manifold and sports exhaust fitted. The car is running a CSI ignition at the moment and I am finding that the low revs on pick up is very poor, especially if going up hill. I am going to fit a 123 ignition to try and aleviate this but not sure which one to go for. The standard 16 curve, is there anywhere that i could get a read out or map of the curves ?. Any help greatly apprecated Keith
