52 Carl -- i guess you are correct -- heated discussion -- 235 --
should be blue to recognize that it is a 235 unless someone wants it to be something else -- from inline 216 -- Beck's--
Valve lash and grinding surface of rocker -- do you realize that those are cut at a 2 degree so they will not run off the top of the valve stem-- it will keep popping back in place if it solid lifters --it will not if hydraulic-- good luck on dropping a valve if cut wrong- usually bad on the ones that are spring fed to the standoff -- Beck's
I cannot figure what part of your posts are quotes from Beck's.
The first quote is wrong information, the second quote might not be so important with a truck engine.
Not all 235s were painted blue.
No truck 235s were painted blue (until maybe a few examples in the few 1959 /1960 and later truck engines that came with a Powerglide transmission)
Not all 235 were high pressure engines.
None of the low-pressure 235s (1953 and earlier car or truck 235s) were painted blue.
Steve, all 1954 truck 235 truck engines were painted gray.
Not all 235s had hydraulic lifters (but that Beck's comment is interesting). I carefully grind the rocker-arm mating-surface on mechanical lifter engines (235/261) to match the original contour. I bet that careful grinding is safer/better than using rocker arms that have 1/8"-1/4" indentations in the mating surface?
Until 1956, only Powerglide-equipped car 235 engines used hydraulic lifters (except for the Corvette 235). All 1956 and later car 235 engines used hydraulic lifters. Almost no 1941-1962 truck 235 engines used hydraulic lifters (except maybe the few that had a Powerglide transmission).
The original poster should post the Engine Serial Number (pressed into the block to the rear of the distributor) and we might be able to help ID the engine. That warning from Beck's might be pertinent with a car 235 engine.
