351 2v to 4V conversion help
#1
I just had my engine rebuilt and installed an Edelbrock Performer Intake with a Holley 4160 with electric choke.
Distributor is stock single vacuum unit but has a Pertronix II installed.
We got the engine started but had some backfire in the carb when trying to restart.

What is the suggested Vacuum connections for this setup?

Someone suggested that I should just leave the distributor advance plugged up. Anyone done this?

Thanks all.

Sounds like your timing is off. Plug the distributor vacuum for setting the initial timing (12 - 14 deg), otherwise connect it to the carb 'ported' vacuum tube. Any other vacuum connections on the carb can be plugged.

I have the same setup on my engine - it's a nice setup.

Ford connected the vac advance to the manfold. On the 2665 intake the hole on to the left of the Edelbrock logo is tapped for the hose fitting. If you choose to use the plug Edelbrock provides for the manifold and instead prefer to go to the 4160 there are both Ported and Manifold fittings. the manifold tube fitting is the one on the front passenger side that sticks out on a 45degree angle from the carb. This also is the fitting you would use with a gauge if you were testing vacuum. All larger one near the back is for PCV...any unused vac tube ports should be capped. note, although Holley claims power valves have "protection" now, they still blow.

Congratulations! I forgot that I did the same thing when I installed the new distributor in mine, otherwise I would have suggested it.

Got a video to post yet? Smile

Another problem popped up.

We got everything working good now except for the transmission kick down won't work.
I bought the kit from Holley but the rod seems to short.
It's not kicking down when you step on it.

Anyone have any ideas? are ther any modifications that need to be done to get this to work?
