Question is, is the 216 as reliable as the 235? I know the 216 has a different oiling system than the 235, and besides cu.in. don't know much difference between the two. If anyone can share some light, that would be great. | | |

I can't speak to reliability but there appears to be a lot of them (216) still running!

Pre is low pressure, which relies on dippers and splashing to keep it interally lubricated. Post is higher pressure and lubes better, which is particularly important with high revolutions.
Another difference is the rod bearings. The 216 has babbited rods- that means the bearing is basically part of the rod. More modern engines have 'insert bearings', which are easily replaceable. You might not have a choice but to have your rods machined for insert bearings or flat out have to replace them, if you rebuild the 216.
One possibility, to keep the original appearance but improve performance, is to switch to a 261.

Don't over rev it and it'll do the job no problems. Most miles I've covered in the 41 in a day has been 420 ( so far ). I'm planning another road trip in a couple of months time. I'll cover about 2000 miles in ten days. If your 216 is in good condition, don't even think about changing it, if it isn't, then that maybe time for a later 235 or a 261.
All the best

If it does need a rebuild, how are you going to use the truck? Is it just for cruising around or will you be hauling a load with it? Will you put many miles a year on it? Do some costings with a 235 or 261 as well to keep your options open.
Cheers
