HEI Limiting Mechanical Advance to 10?
Is there an easy way of limiting the machanical advance in the HEI distributor? I'd like it to max out at 10. I will be running 22 to 26 initial..
I am running 20 initial now with the stock timing curve, no issues, starts smoothly with slight pinging at full throttle so I won't run it up there until I limit the mechanical timing..
This is on a stock, low compression, 1978 454, 781 heads, Quadrajet, 160 thermostat, aluminum radiator, no AC or heater, turbo 400, 2.87 gears.
100% street driven, I like to use 87 octane fuel but I use 89 when its on sale.. It does slightly run better on 89 which is weird but there in no pinging.
