1954 - when did they upgrade to 155 HP?

[Henry A.]

I have the original 1954 235 CI 6 cylinder engine in my car. I would like to know when they changed the cam to make 155 HP instead of the 150 HP for 1953 and early 1954. Does anyone know?

Thanks in advance...

I don't have a "date" for you - although I suspect it was very early in the model year when they discovered that the cam used in the 261 cu in truck motor yielded an extra 5 HP.......

I own '54 Vin XXXX2042 and is the earliest 155hp car ID'ed by Noland.
