I've been running my HEI Progression Ignition for almost 1 year with no complaints other than wishing this was available years ago. I programmed a cold start table for initial fire up and no longer need to baby sit the throttle as it warms up. I disassembled the distributor right out of the box and found quality materials and exact tolerances throughout, it's impressive.
We just ordered and installed a Progression Small Body dist. in my brother's '70 Chevelle, had to bypass the OEM resistor wire with a separate wire running from fuse box 'Ignition' straight to coil for full 12V. Original Tach worked once we reconnected the Tach wire back onto the coil.
With their latest software version we can now share timing tables, maybe we should start a go to thread where we can find share our tables.
