small diameter HEI, was: 90/91 Vette distributor

It all has to do with startup spark, coolant comp spark
and lots of timing for light cruise. With a max of 42 deg
allowed by the software, and six more by the inital, for
a total of 48 deg, it cuts out...

I've since reduced the max allowed to (42 - 6 = ) 36 degrees,
and all is well.
