Basically a stock motor.
Mopar performance dissy adjustable set at 18 deg.with brown and silver springs.Timing set at 20 deg before. I set it with a vacuume guage and it idles realy good.
Rear carbs are factory 1/8 turned out on the idle screws.
6.5 power valve.
Jets in cenre carb are 63.
Car now pings when i step on it should i up the jet size to 65 what are others running or do i have to do something with the rear carbs.

a stock engine does not need that kind of timing. 8-10 degrees initial is plenty. some of the "ignition advice" on this website is pure crap.


Interesting may be i should set it at 8-10 deg initial and disregard the other advice on the net.
It pings with vac advance disconnected and plugged.
My diisy is adjustable set at 18 deg and initial 20 equaling 38.
Should i try stepping up the center car jet from a 63 to a 65.
thanks Steve
