First thing I did was make sure you've been on the forum for a while and you have. I was just hoping you were safeguarded against having a self-proclaimed carburetor Guru take you down a rabbit hole...
is there any reason you would just buy the tunnel ram instead of another carburetor and just buy another 800 AVS?.. it'll be another couple hundred dollars remember putting those Holley style carburetors sideways and getting the correct linkage paid for... The Edelbrock carburetors are much easier and cheaper to connect together..
