rebuilding 235 engine and using 216 oil pan .the engine is 1945 and the pan is 1942 ,the dippers are at agood clearence to oil galleys but the dippers hit the tubes in the channels ,I hate to bend the tubes with out a gage,pulled out the tube assembly and checked all the tube angles all the same they would all hit ,you cant turn it past without bending something - so Im looking for some ideas - ?

As you probably know thee dippers hit because of the longer stroke of the 235 engine. Chevrolet warned that if a new oil pan was installed on a 235 engine the troughs would need to be "adjusted" (they made all replacement pans to fit a 216).
The 235 stroke is 3/16" longer so the piston/rods drop down t 1/2 of that amount lower or 3/64"

Ive put grease in the oil troughs and found that the dippers leave about a 1/4 inch of grease in the troughs with the tubes removed nothing hits ,Ive no way to aim the tubes or to lower the angle of the nozzle ,I hear you Gene when you say the stroke is longer,how critical are the nozzles to be aimed ,I believe just reducing the angle of the nozzles would clear,the channels would have to be dropped at least 1/8+ maybe the only answer is a 235 pan ? Ill try to lower the channels

What would it hurt to "squash" the dippers a little? Make them wider but not as tall. Just wondering. 3/64ths is not much.

This is interesting. About 1954 I purchased a new 235 short block, from the dealership where my father worked. We put that block in my '50 coupe. I don't recall making any changes to the oil pan. I wonder if the short block came with the proper oil pan?

Ashort block did not come with a pan. A comlplete engine did (head,pan, manifolds).
My thoughts ae supporting the pan under the side rails. Then inserting a correctly shapped piece of wood in one trough at a time and pressing down on the center of the trough.

Thats right. I did'nt think that a short block would come with a oil pan. Possibly my Dad picked up a used pan for it. I know we changed it out over a weekend, so things must have went smoothly.
