I just started working at a machine shop part
time...fun! and this job will let me get some of my
engines built that I've needed to do for awhile.
Two things I worked on already, include some Toyota
Land Cruiser engines. One was to finish assembling
a 1964 vintage engine. This one is almost exactly
like a 235, although it's been metricized...so
everything is just a little bit different. There
are some minor improvements, but not many. The
other one I worked on was a later model, I think
from the 70s. I just worked on the head and
manifolds. This head is a 12 port. The exhaust has
individual runners, but had sealing problems between
adjacent exhaust ports...the manifold was warped
pretty badly, and the owner wound up buying a new
exhaust manifold. The newer head has more modern
"bathtub" type combustion chambers, not the funky
chambers of the 235.
I don't know if the newer Toy head will fit on a
235, but it may be something worth playing with if
you have access to one, and some spare time. Not
quite the same as a Wayne 12 port head for a GMC
302, but partway there at least.
