How to identify this early 235 High Torque, digging for numbers and measuring stuff. From, a tip to help identify early babbitted 235's (optional motors in the pre-'54 Big Bolts): Here's a Chevy motor question that comes up all the time - 216 or early 235?
They have very good information on block and head casting numbers as their whole site just deals with engines. Our good friends over at have a great listing of casting numbers that will help you definitively identify your mill. The best way to identify your engine is to check the casting numbers on the head and block. The 261 has a raised set of 'captain's bars' (casting marks) in the block just forward of the starter. Later ('54-'62) 235's and 261's have four screws around the outer edge of the valve cover to hold it down, and a short side cover that doesn't go as high as the spark plugs. How to you tell which is which? The 216's and early 235's have a valve cover held down by two studs running up through the center of it, and a tall side cover that the spark plugs go through. Thus, many have been re-engined at some point with later 235's and 261's. Ahhhh, but what engine is it, you wonder? Good question - the sheetmetal, frame and axles on these old Stovebolts were able to labor on much longer than their babbitted 216 motors. Under the seat wadding, sticks and dead leaves lurks an engine. Quick and easy 216, 235, 261 spotting You've dragged home the truck of your dreams only to open the hood to a rat's nest.
