So essentially you've converted to a 7 pin module outside the distributor, resued the stock HEI pick-up and locked the distributor timing, right?

Hmm, i was going to do some machine work to mate a 4.3 distributor to the 250 lower section, Your way looks a lot easier.

The poor fit of the 2bbl TB to the Monojust was why I was looking to go Clifford, use a water heated manifold (help the fuel atomization here in MI) and then make a very simple mounting plate to bolt on their 4bbl base (I actually think someone sells this, but it's not very hard to make one with 1/4" alum plate, drill, and sanding roll).
I'd also get the better fuel distribution of the Clifford manifold.
