| | | | Joined: Jan 2011 Posts: 16 New Guy | | New Guy Joined: Jan 2011 Posts: 16 | I just now looked at my 235 engine block stamp (55 1st) and it matches the block stamp for the 55 corvette and my head is a 56 number. Im running the 4 speed manual trans.
Is there any difference in the truck blocks and the vette blocks....or passenger blocks? Or is a 235 the same all over for a givven year?
Thanks,

The only difference is the car engine that had a Power Glide transmission was drilled to supply oil to hydraulic lifters.

You can tell by the engine serial number if the 53-55 235 engine was installed/set-up for a truck, car, or Corvette.
The 235 engines used in 53-55 Corvettes differed from other same-year 235s:
- higher lift 261 cam (large truck engine)
- mechanical lifters as used in trucks (even though a Powerglide was used on Corvettes - all other Powerglide engines had hydraulic lifters)
- aluminum camshaft timing gear (as used in truck 261/235 engines)
- of course, different intake/exhaust/carburetors

Would like to see a complete list of differences in the 235 from it's beginning in '41 to 63. I think that would be quite a long list. The captains bar markings above the starter for one seams inconsistant, have a 53 235 with those bars plus 261s and heard of others with a single bar or no bars at all on some 261s. | | |
