Mild 340 timing
by swinger1969 Thu Oct 15, 2015 8:36 pm
I have a 340 in my 69 Dart , Comp Cams 270 extreme cam, Edelbrock Air Gap, stock single point dist , X heads polished a bit. Seems to pop back here & there unless I ease into the gas. I'm thinking timing. What would the ideal timing be on this as it is? Thoughts? Thanks!

Larry, I think you should head down to your friendly Dodge dealer and order up a electronic ignition conversion kit and get that installed first then start tuning. Might want to get the distributor curve kit springs as well.

Or even better, buy a pertronix distributor.

And then, maybe, get the pumpshot dialed in and then maybe slow down the secondary opening .Or maybe slow down the secondary first......

I'd thought about that - know of any problems? Reliable? ( I like road trips!) I've got an MSD "ready to run" in my '40 Ford (SBC) and no box required and it's great. Don't know why their ( MSD) dist for 340 needs a box.

I heard lots of good reviews from guys who had them, the only bad thing I heard was when people bought the cheap Chinese imitation off e-bay. Most of the info comes from FABO(for A-bodies only).
"Don't know why their ( MSD) dist for 340 needs a box." Because Mopars are different-special.

reliability and points shouldn't be used in the same sentence go with the electronic either one is 100 times better than what you have .
