Hi guys, I have a 55 Victoria w/a 272 in it. I've converted to electronic ignition, changed to 8 volts, etc. I had it out for a ride last week. When it warmed up it started to surge as I was driving. I put it in neutral and revved it up a little it stopped. I put it back in drive and took off. As soon as I took my foot off the gas and started to slow down it started surging again. Could it be a vacuum leak or what? Has anyone had this problem. Thank You.
