It seems Chassis Engineering used to sell the exact motor mounts I need, but they are no longer in business. There are others, but they rely on the installer to locate mounts on the frame properly. That is beyond my expertise, not to mention it would be real hassle to hang engine and transmission in engine bay to try and find proper place to locate place on frame and then weld in, or drill holes and bolt in. There is no room for error - you can't go back and unweld or undrill if you don't get it right.

I just want to bolt in or weld in based on some factory reference point, so I can't screw it up. A plastic model of engine and trans would be great, but I know of no such thing for this combo.

Any ideas?

In my opinion, the only accurate way to locate the frame mounts is to install the engine & trans. That way, it's done once, in the exact location, but that's me. Others may have a easier way.

IMO, the Davis mounts are the best ones available today for 49-54 cars. You do need to hang the engine on a hoist in order to locate the mounts properly, but there is a way to make the job easier. Bolt the engine brackets to the engine, then bolt the cushions and frame brackets to the engine brackets. Lower the engine into place and position it where you want it with the frame brackets resting flat on the frame. Then mark the locations for the frame brackets and drill or weld as you prefer. It is almost impossible to screw up if you do it this way.

FYI; after the owner of Chassis Engineering passed on, the family did't want to carry on with the business, and was't even interested in trying to sell it. This was after they had just added some new employees also. BUT, at the ,last moment, Heidt's came in, made an offer, and took control of Chassis engineering. They were said to even retained some employees, even though it meant relocating. There you have it, Heidt's "should" have what you need. They are not retaining all of Chassis Engineering's products. I am Butch/56sedandelivery.

Ever tried to talk to the people at heidts?? biggest jerks ever, their stuff is over priced and when you inquire about buying it they are horribly rude - which tells me their customer service after the purchase would be far worse. No thanks...

Just find a good fab shop to do it for you. I have a 292 waiting to go in my 49, and that's what I have planned - good local shop to make the necessary brackets and welds - done!

Hi Guys, other forum members have done the 292 conversions so maybe they will chime in.
I have only done a 250, which is similar but from memory the 292 has engine mounts that are not opposed.


With all due respect to Ray and Davis manufacturing, those flat mount biscuits are ok for a yard engine like a bench saw or wood splitter but heavy car engines use full size angled engine mounts.

The 292 has gobs of torque and is going to spend its time trying to turn over on its side. Hence the need for big angled mounts up above the crank line.

Cheers kiwi

Before i decided to change direction and go with a 4.2l i6 trailblazer motor and trans, I had mocked up the 292 in the 4door 50. I used sbc mounts from speedway and just moved the driver side back a few inches it needed. Just used the angle brackets that came in the 292 and then bolted the sbc mount brackets to them.

Hi KZHurley, That's pretty much what I did with the 250, except for the set back mount. SBC mounts are easy to get anywhere.

Can you post some pictures?

Sorry but I no longer have the pics on my comp.
I used the universal top hat frame mounts and those biscuit style bushing on that.
I have those style mounts in my 50 2door with the 348.
I don't care for the bushing style mount as they seem to transfer more vibration than a factory mount does.

Mailman just delivered the Davis mounts today. They look plenty beefy enough for me.

Is the 216 block and 235 block the same? I am thinking about buy a set of mounts, then with my old 216 still in the car mark where the mounts need to go on the frame with respect to the 216. Then when the 235 goes in everything should bolt up.

Easy peezy?

Yep. I had a '54 235 in my '50 once upon a time. I used the front mount bracket that mounts on the holes in the top picture. Be aware that some year engines have side mounts instead of the front mount.

Hi James, If you mean the show style that use a horizontal bush and through bolt, I would agree entirely. That's a race car trick that is horrible for NVH particularly if the bush is Nolathane.

Hi Rawbertsun, Biscuit mounts are Ok but big fat factory ones on a mount plate give the quietest smoothest mount usually.

Hi Z28, There are various different styles of passenger car mount in the 216-261 series engines ending in 62'.
First is the timing cover 216-235 49-51', second is the tower side-mount (52-54') which has a triangular bolt pattern in the block.
Then there is the 55' on pattern which is three bolts in the block, but the pattern is inverted.
I don't know what the 216 used in late (Post 52') deliveries had and there may be other styles coming in from truck motors etc.

The third series of six cylinder which is a total engine re-design has three size variants of 230, 250, and 292 for Chevy. The 230 and 250 are the same but the 292 has one mount offset back. All bolt to the block.

Cheers Kiwi

Kiwi, there is another type 2nd gen 6 cyl mount which might be of interest to swappers.

55-57 passenger cars have two holes, one above the other, just to the rear of the timing cover plate. This type was also used on 55-59 trucks. The stock mounts which bolted to these holes are not strong enough to withstand the engine torque reaction, so were always used in conjunction with bellhousing mounts. Aftermarket mounts which bolt to these holes are available for installing 55-57 engines in other year cars which have only a single point transmission mount.

58-62 passenger cars have three holes in a triangle pattern (one up and two down) about midway back on the block. These are easy to tell apart from the 52-54 type, which have two up and one down. 58-59 engines also have the 55-57 holes for installation in trucks. These same 55-57 holes have turned up on some 60-62 engines in addition to the normal triangle pattern. I don't know the actual usage for those engines, but some possibilities might have been warranty replacements and/or parts dept. sales.

3rd gen 250 and smaller engines have a triangle pattern similar (and possibly identical) to 58-62. 292 engines have the same triangle pattern as 250 and smaller, but on the starboard side of the 292 the location of the fuel pump and the mounting holes was swapped, as you already mentioned. This may have been done because of some kind of internal clearance problem (with the fuel pump) related to the longer stroke, but that is only a guess on my part, and I would love to hear the actual reason from someone in the know at GM.

Hi Ray, thanks, I had a gut feeling there was a fourth variation but could remember if it was truck or car.

Can you post an image of that later mount?

Not sure which later mount pattern you mean, so here are links to pics of all three types. On the Davis pages linked you will need to click through the pics to see the one which shows the mounting holes on the block. I wasn't able to find a URL for just a single pic.

Here is the 52-54 type. Note how left and right have different bolt patterns:
https://www.ebay.com/itm/10066-GENERIC-MOT OR-MOUNT...

This is 55-57, also used on 55 (2nd series)-59 trucks:
https://www.ebay.com/itm/10046-235-261-MOT OR-MOUNT...

This is 58-62. The engine shown also has the 55-57 mounting holes:
https://www.ebay.com/itm/10061-1952-54-CHE VY-CAR-w...

Davis does make mounts for the 3rd gen engines, but none of their pics showed the actual bolt pattern on the block. The link below is a 250 from another site so you can see how similar the bolt pattern is to the 58-62 235/261.

Hope this helps clear up any confusion I may have caused.

As long as I'm posting pics, here is one of a 292 showing where the fuel pump and right side mount swapped places (compared with a 194-250). I'm still hoping one of you guys can tell me WHY they swapped places.
