[Diy_efi] Help, putting a 4.3 TBI on a buick 3.8L V6

[Mike V]

Hi Jim,
why not go with a Buick ECM & electronics?
Coil-paks on the Buick have to be better than the old
dissy setup.  Also, the Buick MAF setup is less sensitive
to minor cam timing changes than the Chevy MAP
system.  Just my knee-jerk reaction to the plan.
Cheers,
Mike V
