What can I upgrade now?
Currently on my 318 with stock compression, XE268 cam, headers, relatively stock heads, stock converter and warmed up 904, I am running a Holley 650 DP vac secondary carb with electric choke. It runs well, with no stumbles or issues, but I think it is a bit lean. I currently am running #70 jets, up from 67s from the box settings. The plugs have a slight white shade, but not too bad to denote a major lean condition. I have been running this for 2 months now.
Should I continue to tweak on this, or pull it off and put the Edelbrock 600 vac sec back on? What has the better performance altogether? If I do swap, the Holley will go on my cuda's stock 340 with higher compression (although stock 340) amd of course, the better heads.
I am running 3.23 ratio gears on both cars.
