What year 340? I would recurve that distributor if you haven’t already. My bros 340 didn’t come alive until we took 14 degrees of mechanical timing out and added more initial timing!

The block is a 70 and the X heads are a 69. There was a stock 340 damper with no degree tape on it so I added a tape to it to check the timing. It also has a MSD6al and MSD Distributor. It was set at 22deg initial and 38deg in around 2800. I took the distributor out cleaned it up, ordered new springs, reset it up. I have it set at 18deg initial and 36deg in by 2200rpm.
