Quote: The MP orange box pulls timing out above 4000 rpm , really a poor choice for an ignition box , swap it out for something better .
I ran the Chrome box back in the day. Are they still available? The stock 70 440 Super Comando I had in my Cuda 440 only had like 9.75-1 compression. The car ran 13.02 stock. When I upgraded the motor it was a similar combo to yours except I went with high compression 12 to 1 and a bigger cam 590 purple shaft and I had an 850 DP Holley. The Cuda ran high 11's. I had those ductile rocker arms and basically stock 906 heads. Like I said if it is running right it will easily run 12's.
