Re: 350 timing with HEI

You really should have started a new post, rather than hi-jacking a 5 year old one.....but at this point, I guess it doesn't matter.

The main thing to note here is that the statement "I just installed an GM HEI distributor", means very little. There are at least a dozen different variations of calibration. Just because they all "look" the same and they all "fit", does not mean that they will "act" the same.....because they will not.
You really need to know where the advance curve is tuned to....and be willing to adjust it. For some reason, many guys think that they can pull out the points distributor, drop in the HEI, and they get all of the advantages "automatically".
It's just not that easy, unless you go to the trouble to have your "new" distributor calibrated to match the old one before you install it.
Most of the stock HEIs are set-up to run with ported vacuum...and you don't want that.

Bad planning on your part does not necessarily constitute an instant emergency on my part....

The great thing about being a pessimist is that you are either pleasantly surprised or right.
