if you have somone who is REALLY good at quadrajunk carbs it will outperform both the holley and carter (edelbrock) in milage
the OD tranny will help greatly, as will forcing it in lockup while cruicing

Hi!
Have a LM-1 that is currently using a Wideband O2 sensor but the problem is that if I jet lower I get a problem at light loads.
As far as I understand it the Powervalve restrictions and the jet size should always be the same area when combined so if I put in lower jets I need to drill the power valve restrictions so the area in the jets and the restrictions match again or I will run lean at light loads.
I had 60 jets from the original 66 jets and an earlier powervalve (8hg one and my car has 9.5 at idle) and still I could get it to way past 16:1 in fuel air ratio with the following splutter.
but when I got up the speed (slow as hell so I wouldn't run too lean) it ran fine at 14.5:1 witch I loved. but again it wasn't funny to drive like that and the milage didn't improve overly much for some odd reason.
