RE: tri-power inquiry

Patience is always good advivce. I'd like to contribute a couple of humble opinions on this tri power installation to a '67 390 GTA (of course you mean Mustang right? Was there any other '67 390 GTA? Oh ya, there were Fairlanes....).

Mr. F has it right on with regard to adjusting/synchronizing the Ford tri power. Just follow the FoMoCo shop manual instructions to a T and your friend shouldn't have any problems. I wouldn't consider myself close to adept at air/fuel adjustment but my tri power works correctly and all I did was follow the instructions in that '63 shop manual supplement.

However, make sure the trio of Holleys are rebuilt properly. The man for this is Joe Bunetic. Search "Bunetic" and you'll find a number of links to Ford tri power. Joe did mine and they work perfectly. And they look like brand new.

Now for that Mustang GTA 390 I think there's a couple of minor obstacles he'll face. Vacuum source for the C-6? I think there's just one vacuum port on the Galaxie/full-size Ford/Merc tri power intake. It's on the back of the base of the back carb. His 390 GTA has power boost for the power brakes, right? So, plan for a dual vacuum pick up at this source. Shouldn't be too difficult.

Second concern is with the Mustang 390 Kick down system. I know the Fairlane 390 GT/A used the lever/paddle that actuated off of the accelerator pedal rod to a kickdown lever on the C-6. Nothing to the carb. Now for the 390 Mustang? I've learned from this forum that the '68 & later Mustang kickdown for the FE actuated in a "normal" full size car sytem, a kickdown rod to the carb accelerator/lever. How about the '67 'stang/Cougar FE automatic kickdown? It's important to have a kickdown system for yor C-6 transmission. He's going to have to "fabricate" a kickdown system for the for the Mustang.

The Ford FE tri power system is one of the coolest, easiest multi carb systems ever.

This thread, so far...
