1. Can I reuse my stock intake and/or exhaust manifolds?
Yes, they will both fit. However, they will choke the performance of the cylinder head design. To take full advantage of the performance characteristics, air/fuel in and exhaust out, of the cylinder head, it is recommended that downdraft carburators/manifolds and tube headers be used.
We make and sell a set of tube headers which accepts any of the intake systems mentioned below. They clear either the A or B flywheel housings and the B fuel pump. They were computer designed and engine dyno proven to be the best of 5 tested.
2. What carburation is recommended?
For street use, a single Stromberg 48 or the 2-barrel from a 1955 Ford will be adequate. For a more nostalgic look, we manufacture a finned ‘Miller’ dual downdraft intake manifold of the Burns, Zepher or Ansen style for three-bolt base plate carburetors like the Stromberg 81 or 97.
3. Do you recommend a modern carburetor?
Yes. The Weber progressive 2-barrel (32/36-mm) from a Ford Pinto, gives great fuel economy. Arizona Model 'A' sells this setup.
4. Can I reuse my stock distributor?
Yes, you can. But why use 80 year old technology? First Street Restorations (FSR) sells a new electronic, centrifugal advance replacement distributor.
5. Are insert bearings and full oil pressure required?
No, as long as the crankshaft main bearings and dipper connecting rods babbitt bearings are made of quality materials and you don’t exceed 4000 RPMs, the bearings should be fine.
6. Camshaft recommendations?
Because our roller rocker assembly uses 1.5:1 ratio rockers, whatever lift cam you have in the engine presently will open the valves 1.5 times as much as it does now. Example: .300 inch camshaft lobe lift (height) multiplied by 1.5:1 rocker ratio equals .450 inch lift off the valve seat.
