216 to 235 front mount plate

I posted this over on Chevy Talk and I wanted to try here also. I'm getting closer to putting a '61 235 into my '50 passenger car. I can't (or won't) switch the front plate so I'm hoping someone has a template or a good way to locate the square holes in the lower part of the plate for the old 216 mounts. Then I'll make a couple of "reinforcement pieces" with a round bolt hole for the 235 plate. Thanks, Mark <!--POLLS--><!--FILES--><!--SIGNATURE-->

 

I made a template from cardboard of my 216 front mount and transferred it to the 235. I drilled out the 235 front plate based on the template and it worked perfect. No reinforcement was needed and if it mounts like the truck (which is what I have), you can buy a new rubber mount for it. My 235 is a '53 if that makes a difference.

 

Here's a link to the template:

I prefer them square as well so I drill the corners first with a small drill, then the center, and file square:

 

Unfortunately it's different truck to car. the square holes I need to cut are on the outer edges of the plate. See the arrows on the photo for the approx. locations.

 

why don't you want to switch plates??

 

too many reasons to list.

 

BTT and still need some advise. Thanks in advance

 

Any Chevy Inline guys out there that can help?

 

Just change the plate, you can do it !!!

All I did was measure the distance between the 2 mounts on the frame and then drilled 2 holes in the plate while it was still attached to the engine (on a stand obviously). As I was told on Chevy Talk, the rubber frame mounts will absorb any small differences I had, so drilling accuracy is not as important as it is in other applications. It worked just fine.

 

Hellfish, you just made my mind up and I'm going to do it. I was hoping the locations weren't ultra critical. Did you cut square holes and then add the extra piece with a round hole for reinforcement, to the 235 plate? As for that low1954 dude (my son) I'll deal with him later.

 

In case it matters, I dropped a '60 235 into a '51 car. I replaced the stock rubber bushing/mount (probably), measured, and drilled. I definitely did not make the holes into squares, but I probably used washers. The metal is pretty thick and the undrilled plate is the same as the drilled plate except for the holes.

 

The point of the square hole IMO is so that carriage bolts can be used where a wrench can't get to behind the balancer. If using the other mounts just drill it as wrenching is no problem.

 

No need for carriage bolts. IIRC the bolts thread through the mounts, but it's been a long time
