Default 216 to 235.....

For the record when I say 235 cu. in. engine I mean a full oil pressure block.

The 235 will fit and bolt right in BUT...... the water pump is the issue.

first you need the extra clearance near the front / rad location....

second issue is the 235 water pump installed inside the face of the 235 block is TOO low in relationship to the radiator and reduces cooling efficiency.

The best solution is to install a 216 water pump using the $40 dollarsadapter plate available on EBay. It allows the external 216 pump to be mounted on the 235 at a higher location more centred on the radiator face and gives you the clearance needed. The scary part for a lot of rebuilders is that the adapter plate requires to drill a couple of holes in the block face and tap them....... with care it can be done quite safely...... and it is far easier to do if the engine block is outside the truck.

Once the process is done, it is neat and professional looking and only a very well informed observer would notice the difference.

Like Bob, I have used the adapter plate approach. The ebay plate does require the use of a 1942 or later water pump (originally had 2 holes through the pump backing plate into the block) rather than the earlier pump (that had 1 hole through the plate into the block). Their instructions clearly state this and are also clear that the pulley sizes must match to keep the speed ratios correct. I wanted to use the older 1 hole style pump so made my own adapter plate. You do need to use more care with the orientation of bolt heads to avoid conflict with the 1 hole design but it can be done

My first CMP was a C-15A with a 216. Myfirst outing with it was to a winter reeanctment weekend. Drove it the 70 miles each way. On the way home - on freeway, in 4th and screaming at 40 MPH, the No1 piston went out the side of the block.

Later learned about the splash oiling, and why a steady smooth road kept the oil from splashing as much as it needed.

I found in a junk yard a 1954 235 block. Just dumb luck that it was the two years that the 216 water pump parts would bolt right up to a 235 block with no need for adaptors.

Rebuilt the 235 and installed it with no problem. Intalled it about 5 times, before I realized I had the clutch plate reversed!

Would go in and get about 1/2 inch from joining up...

ANyway, after that was sorted, the rest was simple spanner turning and it ran great.

Default Machine shop terminology.....

Both engine are the same size......in machine shop terminology it usually means......

Short block..... is the engine block, pistons, crank and cam shaft and timing gear with cover....... nothing else is included....

Long block...... same as above BUT it includes the installed head(s) and valve train and usually includes the valve cover and oil pan, oil pump...... DOES NOT INCLUDE intake/exhaust manifold , carburator, water pump, distributor, generator, pulleys,


A full "drop in" would be an engine that has all the accessories attached ready to be bolted in and run.......

Good luck

Cheers
