I've done a tune up. Replaced the plugs (she likes autolites) and wires, replaced the distributor cap and rotor, and installed an "orange" ignition box. Haven't played with the springs inside the distributor yet, and I haven't been able to check the timing. My timing light is busted and he doesn't have one. > She's also running a little hot. That's one of the reasons why I want to check the timing. Once I make sure the timing is okay, I want to flush his radiator and put a cooler thermostat in it. He has a 195 degree thermostat right now. I've told him he needs to step that down to at least 180, but he hasn't bought one yet. I've already replaced the water pump when his crapped out, so I know that's good. Speaking of timing, do any of you guys have a recommendation as far as what I should set the initial timing to, or should I go with what's in the book? I usually go with what's in the book, but I know there are some Mopar gearheads around here that might have some info I don't. He's already running high octane fuel, so I want to be able to take advantage of that.
My first post.
HBS This quote from you tells me what is wrong with this 340."Haven't played with the springs inside the distributor yet, and I haven't been able to check the timing". I would be willing to bet that this engine has the 484 284 MP cam in it. It is a popular cam. But even if it is not the low vacuum tells me that it has to have a lot of initial timing.If the distributor is stock, there is no way that you can have the initial correct and the total correct at the same time without closing up the advance slots.It is advancing too much right now causing the pinging.Fix the distributor first.Barry
