Your stock set-up giving you trouble ? I run mostly the original, stock, assembly line stuff on my cars. I did switch to a 10" diaphragm in my 65, everything else is stock, and I find the performance to be just fine. My 428 uses the stock 11.5" three finger set up and performance is just fine. So...if it ain't broke. Brian
