i have a 1933 Chevrolet truck and would like to change the original 6 cyl for a new or later model 6cyl that will bolt in and give me better performance.Does anyone know what would be a good fit.?
If you literally mean "bolt in"....suggesting no fabrication or adaption, but using existing mounts, etc......that's not very likely to be possible. However with some fabrication it may be possible to 'bolt in' some frame mounts to match the mounts on the engine you select or mounts adapted to that engine. You do not mention anything about the transmission. Again, it is doubtful that your present trans will bolt up to the new(er) engine. And then there is the rear axle. If original, it is the torque tube (enclosed driveshaft) type. It would be my recommendation that you plan on using an engine transmission that were originally used together, or can easily be mated, and a suitable open drive line rear axle ***embly. For example a 194/230/250 Chevrolet 6 from 1963 up into the '80s and a Turbohydramatic 350 or 2004R trans...or for a manual setup, an S-10 5 Speed trans. You could use any GM 3 or 4 speed if you preferred, but they are not floor shift as built, though conversions are available. The nice thing about this year model range of engines is they have the same block/bellhousing bolt pattern as the V8's (and 4 Cyl) meaning your options are all doable with no adapters. Not as much versatility with the pre-'63 engines. Another good posibility that would save space is either the Buick or Chev V6 engines. They are 231 to 262 cubic inches, compact, torque is good and a variety of transmissions are readily useable. Ray
1937-1962 chev 6 cylinder engines will interchange, not sure if this goes back to 1933. In 1937 they redesigned their engine. Maybe they made it to interchange with earlier models. An antique Chev BBS would be more likely to know.
I'm into 235's, but if I were to start over, I think the later 250's would be a good place to go. Easy transmission options is a good reason and they should be easier to find HP stuff for them.
The Chevrolet truck front motor mount is the same from 1932 to 1953 so half the mounting job is done. Use a 216 or early 235 front motor mount plate on a later 235 or 261, or even on a good 216. If you used an engine and transmission as a unit all you would have to do is put mounts under the truck bell housing. There are a few more things you would have to do, but that is most of it.
most of your inline six engine mounts into the sixty's had a two bolt mount on the front below the harmonic balancer and a double mount on the rear bell houseing area if your thinking about a 235 or bigger in your truck you might also want to look at setting your radiator a little bit forward i have a 250 with a 2 speed powerglide in my 38 and the guy that put it in before i got the truck made a crudely built home made mount on the front and i don't even want to look at the ****** mount the fan had hit the radiator and chewed up the fins a bit but radiator is still allright but i also have a new walker radiator that is set forward about 2 inches
