I got me up a nice 62 235. I am going to give it a partial rebuild. The head was already done by clifford last year. The rings need to be done, but, it already has new bearings and a new oil pump. Are there any area's that I need to pay special attention to? Is there anything that makes this engine different from any other motor? I don't have the specs for a full pressure 235, but, my old 42-46 manual calls for 35-45lbs for rods, and 100-110lbs on the mains. Is this right? What about the head bolts? Thanks

Also, what was factory color for that motor

If the 1962 235 came from a car the engine would be blue. If it came from a truck it would be the same gray as a 1947. The truck engine would have solid lifters and the car hydraulics.
Head bolts 90 Ft. pounds

Was there a 235 eng in 62 with a heavy duty clutch avail in the cars??

Thanks. Jim.

Yes, the heavy duty 11" clutch was an option for passenger cars. Required 11" disc, pressure plate and flywheel.

Thanks Chevgene.

Could you clarify my situation?? I have a 62 235 in my 48 with cast date of A202, block cast #3769716, ser #F0205JC. Looking these numbers up, it tells me that this eng came from a truck with HD clutch. The reason for my question is that it has hydraulic lifters instead of solids. The eng was rebuilt and I have receipts for that, which show no change in either cam or lifters at time of rebuild. Also, defination of "Truck", is that to say it includes pick-ups, or something in the heavier range above 3/4 ton?? Per your post if eng came from truck, should have solids.

Thanks for your help.

That's the same deal I have been working on for a week. Look around in a different thread in this same forum.

Jim,
The JC engine was used in 1/2. 3/4,1 and 1 1/2 ton trucks. The 2 ton trucks had a "heavy duty" 235 which had, depending on the year, better piston rings and better exhaust valves,some years had valve rotators.
The actual block casting were all the same.
The JC indiactes an 11" clutch option for the smaller trucks, was standard equipment in the 1 1/2 ton. The heavy duty clutch part was just the fly wheel, disc and pressure plate, and it (the JC) indentiied those parts as they were part of the engine when it was ready to be dropped into the chassis.
Your vehicle may not have an 11" clutch, may be that just the engine was used and you have the original clutch. The car bolt pattern between the transmission and flywheel is different than a truck.
All the trucks had solid lifters. ON the 1959 and up blocks the oiling system for the lifters is the same and hyd. lifters can be used in all 235 blocks as long as the proper cam is used. Why and when the Hyd. cam was installed in the block will probably a mystery. For general driving I would prefer the hyd lifters.
My info shows your block casting number was for a 1960 but that may not be 100 percent correct. That number has appeared in some 1961 and 1962 models also.

Thanks for taking the time and effort to answer my questions. Appreciate it. Am reasonably sure the clutch, flywheel, and pressure plate are from the 48 and know that the bell housing is 48 for sure.
I, like you, don't know when cam and lifters were put in. That will always be a mystery, but also agree that the hydraulic lifters are much easier to live with in my car.

Thanks again Chevgene.

Jim.
