The only issue that has arrisen is I have to "reprime" the carburetor after it sits for a day. I'm assuming she needs a rebuild but at the same time kinda wanted to switch to a four barrel.Any thoughts???
If you do, you will have to switch out all of the linkage. The 4BBL gas pedal rod is different, both in shape and in diameter, which means you have to drill out the bushing that the rod passes through to the engine compartment. The transmission kickdown linkage is different as well.
It can be done, I did it, but I had to really do my homework and make sure that I mimicked absolutely everything from a 4BBL to mine. I have never seen a 4BBL on a 70's van, but my factory service manual has a section for the Thermo-Quad. The donor I used was a 1983 B150 and it came with a Rochester Quadrajet that is currently sitting on my parts shelf and it's not even the original to the van. It's a pain and truth be told I'm not sure the slight benefit is really worth the headache.
Oh, and I got rid of all of my social media accounts one year ago...best thing I ever did.
