Bit of pinking in 4th under load towards the end. I've fitted a 123 ignition to it as it had a Fiat 124 Spider dizzy on when I got it - which caused quite a bit of pinking no matter how I adjusted it. It's a USB interface one that allows real-time curve tinkering. Just need to go to a rolling road at some point.
Cheaper than going to a rolling road is to find a favourite hill and start backing of the static advance (assuming you are running 1.6HF advance curves). I run 11 degrees static advance quite happily on 11.5 compression ratio 1600 HF with Var1016 (Holbay) cams and massive valves...
