i have a couple of 235 engines one out of a car that i want to put in my 52 it a 57 235. i have a 235 out of a truck that has a correct front motor mount. should i drill holes in the original car mount or take off the real motor mount from another engine. that being the case do i have to drop the oil pan to get to the bolts that hold the front mount. thanks Paul

if i'm correctly understanding your question; yes, the pan has to be dropped in order to access the two bolts, but i'm confused with the other part of your question

I think if you can drill the holes correctly, that is the easiest way to go. I don't think there would be any point in swapping front plates if you didn't have to.

Save yourself a lot of work and just drill the front plate. You would also have to remove the cam to do the switch. Just stand both motors on end and transfer the measurements,,,away you go.................
Good Luck,

I would drill the front motor plate.There is a lot involved with removing the front engine plate.

Are you planning to overhaul the engine before it is installed? If so, it would be no big deal to swap the plate, other than dissassembling the other engine. If not, then drilling to match will be just fine.

hey lb - are there pics available to see the diff between the '57 motor mounts vs the earliers?

There are 2 good tech tips to help with the front mount modification:

If the holes are made square carriage bolts can be used as was original in some cases.

thanks for all the help drilling the holes it is. The body is off the frame so i will mount the engine and put in the bolts for the rear mounts then drill up into the plates to mark the holes. does that sound like a good idea.
thanks Paul

Thanks for the information. I have a 216 from a car that I was going to use in my 53 pickup. I need to drill the holes and was working on ideas to do it.

Like you wodniw5, I was thinking of dropping the engine onto the frame of the 53 and marking where the holes needed to be.

Do I have to use carriage bolts or can the holes be round and I use hardened bolts?

I have a full pressure 235 in the shop being rebuilt. It will have the correct front plate so this 216 is a 'driver' engine.

Thanks for letting me get in on this.

Wrench access is limited near the balancer so square holes will hold the bolts in place when tightening but either can be done. Mounting the engine in the frame only to locate the holes sounds like way too much work. I can confirm the template linked above will locate the holes properly provided the holes are laid out to equally straddle the crankshaft centerline. Also from the autopsies I have performed the oil pan nearly always has some degree of sludge in it so I would remove the pan any time a used engine is to be flipped upside down.

Good luck.

flipped upside down? why would someone do that without first removing the oil pan?

It's probably on an engine stand.
