Hi Terry,
Just one (1) past experience that I think worked with my 1930 Briggs Town Sedan.
First I called Mr. Stipe's Company to tell him exactly what I was planning to install, what I expected as far as being somewhat close to originality, and asked their advice on what cam to buy.
Told them I was already having the flywheel lightened, crank counterbalanced, maintaining original size SS valves, plus providing other items below, and after their recommendation, I bought the Stipe 330 cam.
With a dial caliper verifying lift, Mr. Stipe's cam was found to be made to perfection.
Provided a B distributor and a B carburetor with this 330 cam accompanied with the Police Head that came with this Model A and installed a new 3:27 ring gear.
As such, verified gas mileage is 20 mpg in stop & go traffic ..... never tested on an interstate straight run ...... never had to shift to 2nd in hill country or for crossing Mississippi River bridges or their up-ramps.
Only drove up to 55 mph ...... accelerator not yet floored, so have no idea how fast it can go. Keep rebuilt A carburetor and a rebuilt A distributor in trunk, both of which can be switched out in minutes if one wants to see more A originality.
Reduced rpm's with a 3:27 can mean less piston ring wear, cam wear, and Babbitt wear in addition to distributor, generator, and water pump wear.
If you call Mr. Stipe's place, you will obtain professional cam responses.
