Miller Hi-Speed Head - F.A.Q.
1) What carb: For street use a single
Stromberg 48 or the 2-barrel carb from a 1955
Ford will be adequate. For a more nostalgic look,
I manufacture a finned ‘Miller’ dual
downdraft intake manifold of the Burns, Zepher
or Ansen style for 3 bolt base plate carburetors
like the Stromberg 81 or 97.
2) For a modern carburetor the Weber progressive
2-barrel (32/36-mm) gives great fuel economy.
I sell the intake manifold, linkage and air cleaner
for this set-up.
3) Exhaust: I make and sell a set of tube headers
which accepts any of the intake systems mentioned
above, 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.
I also have a Duke Hallock style cast iron exhaust
manifold for my head.
4) Distributor: I sell a new electronic, centrifugal
advance replacement distributor and it mounts
in the same location on the engine only higher
in the engine compartment because it mounts on
top of the Miller Hi-Speed Head.
5) Oiling system: As long as the crankshaft and
connecting rod babbitt bearings are of good quality
material and workmanship plus you don’t
exceed 4000 RPM the bearings should be fine.
6) Camshaft: Because my roller rocker assembly
uses 1.5:1 ratio rockers, what ever lift cam you
have in the engine presently will open the valves
half again as much as it does now. Example: .300”
camshaft lobe lift (height) multiplied by 1.5
rocker ratio equals .450” lift of the valve
off the seat.
