Re: Set timing on 1988 Ford Crown Vic 5.0 Litre ??
Depending on how hard you like to run it, I'd set the base timing at 12-14 degrees and go from there. To set the timing you take the little two prong plug out of the distributor which disables the speed timing advance. then you put your timing light on the #1 plug wire, the first cylinder on the passenger side, start the motor, and see what you're at. stock timing is somewhere around 8-12 degrees btdc. mustang trick is to set it to about 14. shut the motor off, put the plug back in, tighten the nut back down, and take it for a drive. if it pings too much (basically at all) either put better gas in it, or the most sensible solution is to retime it with slightly less advance. It's all kinda relative really, there's enough play in teh stock timing markers, that 12 degrees might not really be 12... that's why I always tuned mine by ear. It's really quite simple once you actually do it.
Good luck, and have fun with it.
