[/URL]my buddy got this setup relatively cheap. Its a impco 225m-2 with model L and vff30. I have setup a dual 425 setup on a 454 but this setup has a lot more to it. I can't figure ou thow to bolt it to the manifold. Manifold bolt pattern is 3 1/4x 1 7/8 and the carb pattern is 3 3/4x 2". is there such an adapter that exist. Also on the model L mixer that is a vacuum valve on it with two electrical connection. What is this and what hooks to it.
 
I think all these country boys ate keeping quiet at the risk of coming across like pirate4x4.... we need more info, but it appears you have a 2 barrel or v6 setup and you are wanting to install it on a v8. Im sure it can be done but may not be the best idea. Some of the propane kit providers are your best options for the tech you desire.
 
I'd say you'll have to build an adapter.

Try google searching the part numbers/names on the black thing you're talking about. I don't know what it is, and the camera flash washed out the label, so I can't see what it says.
 
We are trying to put it on a 87 jeep yj 4.2. It had a carb swap done and we couldn't get it to work right so he wants propane. Its a stock manifold
