Jack, I told Fulper the other day that when Schmutz was alive and racing he had to get a box right from MSD. Chevy V6s aren't odd fire, they're semi-odd fire.

From Wikipedia:

"the 200 cid and 229 cid, have what is called a 'semi-even fire' sequence which alternates between 132º and 108º. This comes about due to the 'slipped disc; crank pins; each pair of rods are offset by 18º. The design of the crank required the connecting rods to have 0.050" narrower ends to fit onto the available rod journal space due to the material added to the cranks for strength."

"The 4.3L V6 engine has an even-fire sequence, occurring 120 degrees apart. This is accomplished by having a larger 30º offset on the rod journal pairs."

Buick V6s from 1962 to 1976 were odd-fire engines. Buick V6s from 1977 on, were even-fire engines, with crank pins offset 30 degrees for each rod pair, like the Chevrolet 4.3.
