advanced timing school please

I'm far from the expert, LOL on timing. So far as recurve, I have never used them, but FBO ignition makes a kit with a "limiter plate." Other than that, your only options are welding up slots or buying an aftermarket distributor.

Also, be sure not to get confused by "distributor degrees" and "crank degrees." I tend to "think" in crank degrees. When you look up distributor specs in all the old Motors or service manuals, they are expressed in distributor degrees. This is "half" of crank degrees. If you look at a mopar advance 'top hat' many had a number stamped. This is distributor degrees. Something, say, "15" is a long slow "smog" advance, -----30 crank degrees. Also, any distributor built after about 68 is a "smog" curve, getting worse as newer. Rebuilts are questionable, as you never know what you get LOL
