Spark plugs for non-performance 383
Hi,
Does anyone know what (and is there a chart anywhere on the web) for what plugs to put in a 383 two barrel ?
We have a set of Autolite 75's (which I believe you can't get anymore), but topics I have seen in other forums (Moparts) talk about Autolite 85's, but these appear to be for performance engines.
Obviously not looking for the latest most expensive super plug, just something new for a 224,000 mile engine.
Thanks.

Mostly do motorway driving in the Pit so use the NGK7s , can get away with the #6s when poodling around & the #8/9 when on the bottle.mopar_mark wrote:I always found success with the NGK's, would try something like a B8ES
Anyone running a hottor plug than a #9 (champion) will probably notice the insulator nose cracked/spotted & the heat mark on ground strap will be white & pretty close to the threads on base of plug ..................as said , was ok back in the day , simple fix will be to drop to a lower heat range plug , too low & the plug may foul , a lot better than destroying the motor.
Above is based on a stock motor with stock timing.
Plugs are cheap.........
