Perhaps someone over at the Stovebolt.com site will have an answer for this question.

@bert-askes Are you sure the engine in your 1935 pickup is a 216? The original engine would have been a 207.

207 exhaust manifold dumps at the back, 216 exhaust manifold dumps in the center. The original 4 speed transmission for 1935 would have a reverse lock-out lever beside the knob. A 216 engine could be paired with that same transmission or the later SM465 4 speed without the lever.

You can make an engine from a Peterbilt fit into a VW Beetle if you set your mind to it. The important questions are "what has already been done? With what has it been done? What modifications have been made to date?

We can help more if we know more,

Truck was recently purchased and I have done no modifications.  Got engine running and drove it around the yard.  Engine definitely not original.  Poorly installed with braces welded at rear to stabilize engine.  Sent engine numbers to this site and it was determined it is a 216.  Transmission is 4 speed.  Will this transmission bolt to a 235 to replace the 2 speed automatic?  Is there enough difference between 216 and 235 to make it worthwhile to exchange engines?  The 235 is from a 1962 car with powerglide transmission.

I think the bolt pattern for the clutch housing is the same for 216 and 235. Early 216 had 4 bolts attaching the flywheel to the engine. This was later changed to 6 bolts. I think the 6 bolt flywheel will work on the 235. The clutch housing/flywheel combination will be necessary for using the 216 starter. 

Remember to install a clutch pilot bearing in the crankshaft of the 235. A Power Glide engine would not have one. 

My opinion is that for the typical way we use our old cars, you will not see enough difference in the two engines to make it worth while to make the change. I drive my 1935 and 1936 Chevys with their original 207 engines and am happy with the way they perform. Maybe cleaning up the installation of the 216 (if it seems to run well) would be the more practical path. Sounds like you will want to do this in either case. Good luck. I hope this helps.

Very helpful.

Will take your advice.  Thanks Mike!

Mike,

I have a 216 removed from a 1953 1 ton dump truck. It has the bell housing, flywheel clutch, pressure plate, stomp starter fittings and 4 speed transmission. The engine has less than 3,000 miles on it since being rebuilt by Jasper. I do use the truck for it's intended purpose. I am switching to a 261 engine and rear end from a late model RV with higher gear ratios because the truck will only reach 50 MPH with a tailwind when loaded with materials. If you are not looking for highway speeds or don't intend to use the truck like I use mine, you may want to consider staying with a 216.
