I'm planning to re-build and hop-up my 1928 Model A 4 banger motor in a few months time. I want to be competitive at VHRA events and tour at reasonable speeds. I'm thinking about a lumpy cam, counterbalanced crank (new with modern bearings) oversized intake valves, Thomas 6:1 head and Thomas dual intake with 2 Stromberg's. I'm also considering a Mitchell Syncro box and overdrive, funds permitting. Does anyone have any useful thoughts or advice on this subject, my research says the above is the way to go but I'm trying to get a general picture of what's good or bad, worthwhile or otherwise. Any input will be very gratefully received, thanks.
