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.
