Correct ,and apologies on my part. This is what I should have posted.: http://www.google.com/url?sa=t&sour...eMTRyJfhNCmMGoSCPw7zLAA&bvm=bv.76802529,d.cGU
However a few number of posts here related to adding torque multiplication through a rear gear change,possibly a converter swap. I see, you have a bunch of aftermarket goodies added. Have you even bothered to tune, what you have yet? Timing curve(initial,2500-3000)/ carburetor float level/idle mixture/accelerator pump/ jetting ? These need to be done /revised every time you change the combination. Have you done any,or do you want to just add a cam?
