That's kind of a loaded question there. The early 235's, ie 48's, were babbit/low pressure engines. In appearence, you'd never know the difference between one of these, and a 216.
Now when you get into the later 235's, the valve cover's are different, held on by 4 bolts into the head, rather than the two acorn nuts on top. Also, the side covers are different.
On the early 216/235's, the side cover was tall, and went up and around the spark plugs. The later 235's it was a short cover that stopped well below the plugs.
With all of that said, a 48 - 1/2-ton would have normally come with a 216, as the 235's were made for the larger trucks.
I have a 48 - 235 in my 52 1/2-ton, good motor.
Hope that helps. | | |

235's have a intake that looks like 'some strong guy' grabbed it and twisted it. | | |

If you are comparing 216s and 235s from different years, this table might help If anyone sees any mistakes in the table, please let me know. Tim Oops, the info in the table is for USA Chevrolet engines. | | |
