What should the ignition timing be on a 352 with pertronix ignitor and a 268H comp cam ?I have stock pistons and ported heads with a 600 carb on a stock intake The problem I'm having is the car idles pretty good in neatral but when in gear it damn near dies
If iI set the idle decent in gearand then go to park it will run away
Start your timing at about 8* BTC on that 352 with the pertronix, then bump it up a degree or two until you get the best overall performance while driving. I think your range should be between 9 and 12*.
I posted on the garage by accident but in short I changed the carb to a 750 just to try and it seems a lot better . It is possible that I fixed a vacuum leak because I changed the base gasket I also advanced the timing to about 11 and that helped too I still could get more timing in because it still doesnt ping or rattle under acceleration.
