Re: [HSS] Can You Identify My Block?

Unknown

It is a side-valve Hudson block most likely. These were in two

configurations, first with a hole through the centre of the water jacket and

the carburettor mounted on the left hand side, then in 1923 they changed

over to a Stewart carburetoor which was mounted under an inlet manifold on

the right hand side. There are three different "F-head" blocks - the first

in early 1927 had the exhaust valves in the same position as the earlier

side-valve block. the second in late '27 and '28 models had the exhaust

valves shifted on cylinders 1,3,4,6, and then in 1929 there was an extra

hole in front and rear on the right hand side for lubrication mist to go up

to the top tappet cover. You can use a late-'27-'28 block on a '29, and

vice versa, but the early '27 won't trtanspose to any other model.
