Newbie here again. I am still collecting books and reading catalogs, and watching videos in preparation for dismantling my car. I have noted the availability of 12 volt conversions, new distributors, improved carburetors, high compression heads, oil filter kits, and exhaust headers all of which will make the engine more powerful and the car go faster. I have noted several apparently credible persons comment that it is risky to beef up the Model A engine too much, because the center main bearing is a known weak spot. Do owners really make numerous such upgrades, or do they normally choose just one or two to solve a specific problem?
