The oil pan is the same from 1940-52-this should broaden your search.If the used pan is from a 235 the troughs will need to be raised slightly due to the shorter stroke on a 216.

Hey Chevygene ,, is the trough height the only difference ? Reason being ,. I just found a NOS '48 235 short block and want to fit it up to my '40 when the 216 wears out . but I only have the 216 sump just now . If it is just the trough height difference then I can modify a spare 216 sump to fit . Thanks . Tom48 sorry to sabotage your post with my question , but it just seemed too opertune . Thanks .

There were different demensions for the 216 and 235 engines -The longer stroke of the 235 caused the rods to come closer to the pan troughs and the gauge had two positions.Without a gauge I would guess that the trough would need to be lowered 1/2 of the amount of the longer stroke-or 1/2 0f the 3/16" increase or3/32"..Some type of measuring device could be made for this adjustment if the proper dipper/target/trough heigth gauge can be found.This will prevent the rods from striking the troughs.
The 1940 head can't be used on that 235 engine so try to find a good 1949 to 1953 216 head (1950-53 prefered)-a 1941-48 could be used but has the small 10MM spark plugs.1950 and up has the larger 45 degree exhaust valves and 14 MM plugs.----1950 and up 235 head will not work-1940 head would actually fit but has domed combustion chambers due to the 1937-40 style domed pistons.Use of a 1940 head would give a very low compression ratio.A few other minor parts would also be needed such as valve lifters and push rods. :)

Thanks Chevgene , 3/32 is a small amount , maybe I can adjust something that amount . When I got the NOS short block , I also got a sumpguage set , so when I get the oportunity to drag out a spare 216 sump , I will see just what bits measure up to what spec . Also , last May , I found a NOS '40 216 bare cyl head . SO .... the plan is to plane off the 0.187" that is required to make a 8.5:1 engine of the 235 dipper. That should help the engine run on todays gas. I am looking forward to this project .

Update . The Kent Moore oil trough pipe gauge # J-969-1A that I got looks like it is definately for the 216 engine . However , I think I can use the 216 sump with a 3/32" shim and have the clearences OK , but I have to check the fit (screw aglinements) to the block first. More later .

Terrific Chevgene , does anyone out there have the 235 gauge set that we can do some comparative measurements off ?
Tom48 did you notice that the ebay oil pan has no oil tubes in it ?
