what is your timing set at? Initial and total and what octane and compression are you running?
I never made it past the machine shop. both heads had the usual Magnum head crack between the intake and exhaust valves.
I hope you magged your heads before you put them on, or you might get a big surprise.
yes i did and they are the car. thanks for concern.....
opps they are ON the car
I am running an accel dist. I have not heard a ping yet. And I am not kidding that my total timing at 3000 rpm with the vacuum advance hooked up is around 52*. I was told by a couple of guys on here that it is fine. Should I plug my vacuum advance and just run it mechanical at around 34*?
Badart vacuum advance does pull the timing up to a high amount as you see but it's only there under light throttle if it's hooked to the correct port on the carb. When you floor it there's no manifold vacuum to pull the advance canister so the total timing will only be what ever your mechanical timing is. That's why it doesn't ping at WOT. Vacuum advance is mainly to help gas mileage so if you unhook it you'll loose mpg.
