chevy 235 I6 interchange, advice

[53chevy210]

do the older inline six mtors share anything with newer 250, 292, like motor mounts, flywheel, manifolds? I know the bell pattern is different, but not much beyond that. Also what trucks did the "pressure" engines come in? I'd like to have an improved oiling system over the babbett oil pump in my '53.

The 53 Chevy trucks is when the pressure oil system came in. I am still learning about inline 6's right now and don't know a lot about them at the moment. If I found out anything else I will let you know, I did find some books at school about the inline 235 engines and how to build them to get major horsepower.

The high pressure oiler 235 first appeared in trucks in 1954. They share the same engine mounting, size and placement as the 292, a standard Hot Rod replacement. The manifolds, intakes for 235 fit only older engines, I believe, like the 216. Not compatible with 250 or 292. This engine remained unchanged until 1962 when the engine was reconfigured and was eventually replaced by 292 in trucks over 1 ton and the 250 in cars. I have 2 complete engines for my 1954 1/2 ton 3100, still under construction.

Wasn't the 235 first in 1953 trucks not 54?

I am not compleatly shure, I think so but, it deffinetly has the newer head ( valve cover has studs on the outside flange rather than the '50-'52 235 with 2 studs on the top, like that of a 216 ).

[FMXhellraiser]

Yeah plus the numbers on the head said it was a 235 but from a 54 or 56 one of the two (I can't remember) so maybe the guy changed it or something. Not sure, the guy got my letter I put in his shop drop box so hopefully I will get a call back within the next two weeks.

The inline chevy six 235 was built in 1941. The pistion was not a 3 1/2" like the 216.5 but a 3 9/16". Part # 3688882 Std. or 3688887 for.005 O.S.

Sorry for the extra i on piston. I 1953 the in line chevy six 235 ci. was a full flow to the rods and not a splash system, like before.

[FMXhellraiser]

tjc, that is what I wanted to find out and that is what I thought. Thanks a lot man, now I know for SURE that it's not a splash system.

This is a very good way to I.D. all in line chevy sixs. From 1937 to 1952 the side cover on both the 235 and the 216 motors "the side cover (covered the spark plugs holes and up to the top of the head) The 235 motor from 1953 to 1962 the "side cover was one long cover and stopped before the spark plugs". In 1963 the 194, 230, 250, and the 292 came out . The 194 thru 292 have two side covers. The side covers are the same for the 194 thru the 250. The 292 is about 1 1/2" taller because of the 4.125 crankshaft. The 194 thru the 292 has a screw on oil filter. Good luck. Tjc
