I have a 65 tri power manifold that I was thinking about using for EFI. It
has the small center carb and big outer carbs
I plan on using Cadillac TBI's (4.1 L) for the outside TBI's since the Caddy
used a throttle kicker instead of a IAC. The throttle kicker would be left
off since the outside TBI's don't need idle control. The middle TBI would
be a 5.7 L
Type with IAC. OF course I haven't checked if it will all fit. I will use 2
external drivers triggered from each INJ output
Another throttle position sensor will be used to tell the driver to turn the
injectors on at approx. 70% throttle opening
Or I could use the TCC/kickdown output of the 747 to kick the drivers in. A
progressive throttle linkage will finish it out.

Yo--why not find a tri-power manifold, and do a 3x2 TBI ??
