Not at all if anything it would hurt hot start if hooked up electrically it adds 5 advance when energized and also it is in line with the throttle solenoid (this NOS 1969 1/2 Road Runner Super Bee 440 Six Pack Idle Stop Solenoid DR1114420 NR | eBay look what it sold for) then when it is turned off it retards the 5 degrees, super expensive set up and hard to find working, I could not have enough of them last year, mostly RR guys seem to run it since it was stock on most of them.
