Any Results?

[rippedvinyl]

I have a 72 225 1bbl daily driver. I also have the complete for a super 6 2bbl that I may install to get better gas mileage for my commute. I have read that this will increase my mileage, but I have not seen any posted results.

I was wondering if anyone has any results from their own conversion?

I went from 19/20 MPG to 27 easy when I removed the one barrel and opened my exhaust, Do a 2 1/4 down pipe all the way to the back will take the potato out of your exhaust and give you HP for sure when you go two barrel, I used a small 390 cfm Holley

On your 75 I would think 5 MPG min.
