Thumbs up Re: Tri-power issues

The other tri-power EFI I was looking at was Autotrend EFI in Diamond Springs CA.
!!! DAMN !!!

They have their shiat stacked in one neat pile ...

The trouble (I see) with the other vendor is their using whatever injectors and/or sensors. You want at the minimum BOSCH QUALITY parts on the setup and a ECU that can be accessed easily and modified/tuned (if using GM DELCO sensors try not to use their WEATHER-PACK CONNECTORS as that draws away detail).

I also noticed that they describe modifying an intake manifold if needed. If your intake is cherry and nos. correct, you may want to find another take-off to modify (IMO)

The FE FORUM has a wealth of info and the guys there are dedicated.

Please keep the board updated as to which rout you choose to go with.

BTW-

If you built say a Q-CODE 428 (torque) for the street with reasonable CR and cam events, this system would give you one hell of a driving experience.

I would maybe use the cast shorties but have an H-PIPE made to accept the O2 SENSOR as I would hate to think of locating an OEM H-PIPE (inlet pipe) if later the car goes to full restoration.

Maybe consider a set of tube shorties for the street to save the OEM manifolds.

It actually drives OK, even with California gas, except for the hot start.
The electric fuel pump is going to solve most of that. There are other things to do to make it more efficient if not purely stock.
