Funny you should mention DUI ignition. The Supercharged Studebaker I posted about in another thread was on the dyno just before Eric's Pontiac. The Studebaker was a special GM DUI HEI grafted on to a Studebaker base. It worked fine until they turned up the boost on that engine. When they increased the boost above 8 PSI, they began to have some misfire and ignition issues. We decreased the plug gap to about .022" and it ran better but not as well as a point ignition Studebaker distributor they had as a back up triggering an MSD 6 with Blaster coil. Just don't think HEI has enough spark energy for boosted or high RPM operation. I could certainly be wrong, but the last two engines on the dyno have had HEI issues. Don't know the history of the Studebaker DUI, how old or how many miles on it.
