Hello All,

I'm going to be swapping out my 207 with a 1954 235 engine soon and have the 235 in the machine shop now. I have a few questions and if anyone can share any known "gotchas" that I will face along the way, your guidance will be greatly appreciated! I've sourced a 1937 truck bellhousing in order to retain the original pedals and I'm told the 235 and original 1936 3 speed transmission will work with it. Can anyone validate this? I'm also wondering what year clutch and components, starter I will need to source to work with this setup? Lastly, if I want to go with a later model transmission, what years will work given the constraints the 37 bellhousing may pose?

Thanks in advance!

Because 1937 used a carbon throwout bearing(last year for this), the pivot location for the clutch fork is not in the correct spot for a fork used with the ball bearing throwout bearing needed for the clutch that bolts to a 235.
You need a 1938-46 bellhousing, or maybe modify the 37 bellhousing.
You will also need to change the transmission front bearing retainer to except the 1938 and later throwout bearing.

See the USA in your vintage Chevrolet!
