History lesson on 283 and 235 please

[bpmcgee]

Hi,

The '60 for which I'm planning a frame-up restoration has a trademaster ('60 or so 283) in it. From the factory, it came with a 235.

I have 3 options in engine rebuilding -- Find a 235, use the 283, or use the '70s era high-nickel 350 block that I have. I'm curious, first, what the differences would be between the 283 and the 350 (I think a different rear seal at least?) and the idiosyncracies of the 235 -- I don't know much about the inline 6's.

Thanks!

Brian
