I shouldn't be sticking up for Chevrolet on an IHC site but the 235 was a very good motor. I have rebuilt and used several. The 216 was the babbit bearing motor and the 235 was the split bearing version. The first Corvette motor was the Blue Flame 235 six with dual carburetors. When I was a kid my older cousin raced one at the local drag strip and did well with it.These motor can be hot rodded! Another version of the 235 was the 261 which went into school buses and big trucks. I pulled the tired 216 out of my 1945 Chevrolet G506 Army truck and replaced it with a 261 and it moved that behemoth of a truck around quite well! While the 235 was anvil reliable when Toyota got a hold of it they screwed it up. They were well known for shredding their rings and valves . My 78 Cruiser had to have both done in under 10,000 miles under warranty. I sold it soon after and bought a used 61 GMC 4x4 with a 305 V6, one of Jimmy's better motors too, it served me well for years.
I love my Binder and want to keep the motor original as I can so no Chevy motors in it but if push came to shove I'd look for a Ford 300 cu. in. six to put in it, but that's a whole other story!
