[Gmecm] '747 and multi=port

[Dave Harvey]

David,
My 91 GMC pickup was originally TBI w/ 1227747. I installed an Edelbrock 
multi-port injection sytem on top of an HT383 engine. The Edelbrock uses 
the '747 to bank-fire the injectors. I'm 99% sure the injectors are 
wired in parallel in 2 groups of 4. Pretty slick setup.
