GM 292 Straight 6 Engine Mounts Explained. EP.14

In this video I will show you a side by side comparison of the 292 engine mount position to the 250 engine mount position. We'll also take a look at the frame stands for the 292 in the chassis of my 79 C10 to illustrate just how far forward the stand sits in the frame compared to other engines.

Good Info,thanks. I'm swapping in a 350 SBC in place of a 250 L6. I noticed the "6", and "8" stamped in the frame stands. Wanted to make sure of the proper location for the motor mounts for the SBC.

Well, I’m happy that someone finally explained the difference. I have been told I had a 292. But I know now it’s a 250. Especially when it comes to motor mounts. Great video I love you clean shop Now the Chiefs cap 🙉🙉👍🏼 Thank you

[@SquaredAwayGarage]

Glad you found the video to be helpful. Isn't amazing how much conflicting information a guy can get for something that seems so simple?

[@tracicreutzburg2478]

Thanks for being so thorough and informative. I have a 51 Chevy 3100 that has a 250 in it and for some reason a previous owner ran it with out side motor mounts. The frame is original so I am researching ways to correct the problem. Thanks again and GO RAIDERS !

[@SquaredAwayGarage]

It is my understanding that some older chassis and engines used a different motor mount. I have never worked with one of these setups or seen one in peraon, but I have seen some pictures. The mounts I'm guessing you may have are bolted to the very front of the engine. Sound about right? If that is the case, what you have may be perfectly acceptable. Do a little research and see what you can find out.

I'm in the middle of swapping in a 292 now. This video was extremely helpful. Thank you

[@SquaredAwayGarage]

Glad I could help.

[@braddenning1617]

Good info ,I didn't hear you mention that the 292 has a taller deck, I did a 230 to highly modified 292 swap , depending on what your building check the clearance at the fire wall, I had to cut my fire wall and recess it 2" deep , I cut it at the base of the block and had to go up to the pinch weld of the cowl , I got the tallest valve cover from Tom Lowe and still had to put a 3/4' spacer to clear the roller rocker set up and stud girdle . Just keep that in mind for you guys building a performance or race motor , Mines pushing close to 400HP AND 418 on torque .

[@SquaredAwayGarage]

Correct. I was trying to concentrate on just the motor mounts. Didn't want to talk about to many other details and make the video longer then necessary.

[@DANIELROMERO-cv3tu]

Any other pointers would be gratefully appreciated. On a 250

[@davidgridley3643]

Good info and great video quality

[@SOU6900]

When replacing the fuel pump on a 350 in a K2500 squarebody you wish the passenger side mount was somewhere else. Or that's my feelings on the matter anyway. Though it also didn't help that the suction and return line ports didn't point the same way on the replacement as they did on the original.

[@user-sc1ck6ec8f]

The truck 292 inline do fit V8s and bolt right onto to frame all the way to 89 i don't care what any body says I've done it. You can also use a 1989 Chevy truck cross member will fit a 1962 1963 1964 trucks and so on and so on

[@SquaredAwayGarage]

You are correct (ish). You can bolt them into trucks up to 87 (US Models) and up to 91 in Blazers and Suburbans. But you either need to modify the V8 frame stands, specifically the passenger side, or use correct engine specific stands. Sounds like you did some customizing of your V8 stands.

[@jonseredchainsawguy2541]

I am considering swapping the 350 in my K20 to a 292 or a 250. Fuel economy and reliability being more important to me than horsepower which would you choose. Sm465 3.73 no towing but the truck bed gets used for hauling up to a ton on occasion.

[@SquaredAwayGarage]

Sounds like you still work your truck. For that reason, I'd probably search out a 292. I assume you'll want to freshen up the engine before you install it. So consider a small cam. Between a little cam upgrade and a new intake with a 390 or 450 carb (some folks even go larger), the 292 will wake up quite a bit. Here's your big challenge though....the K20 (as in 4x4, right?) has a engine stands that are much harder to come by. I would start this process by searching for those pieces first. If you don't find them, it may change your mind on the 292.

[@luispina4012]

Good information...

[@BoneHeadGarage565]

Where did you get your Frame mounts. I got a 66 last January and the mounts are Jerry rigged. It seems like the only way to get a set of mounts is to have a donor truck.

[@SquaredAwayGarage]

Everything you see in this video is in my 79 C10. So the mounts look different than what you need for your 66. But all the measurements and setails still apply. 292 mounts can be hard to come by. Mainly because people pull them to install a v8 and don't take the frame stands and motor mounts out and keep them with the engine. I found mine in a salvage yard. Sometimes they show up on Ebay. Sometime they come up for sale in one of the inline 6 Facebook pages. You have to be quick though. Lots of folks looking for them.

[@tinoflorentino3577]

292 has stargared motor mounts

[@SquaredAwayGarage]

You are correct.

[@afonsoschannel]

Thank you so much. The best video on the motor stands ... I am removing my 292 out of my ex postoffice Grumman Van P30 1984...I'm putting in an LS, I knew something was up when I looked at all the suburbans another C class pick up trucks, I noticed that the motor stands were in a different location on the passenger side I dropped the motor in and knew something was up even with all the LS adaptor plates there was something wrong thanks for the info I really appreciate.. Do you have any info on the clamshells the difference on truck versus car. The distance from the flat plate to the centre of holes?

[@SquaredAwayGarage]

Unfortunately I don't have specifics beyond what I shared in the video. When it comes to all the possible combinations of engines and automobiles, there are probably more possible configurations and details than one guy could ever keep track of.

[@user-sc1ck6ec8f]

The 63 C10 283 V8 had the same as the straight 6 leg mounts from 64 to 68 and should have the holes in the frame for either or

[@SquaredAwayGarage]

The small straight 6's (194, 230, 250) of that generation all used the same frame stand position as the V8's. Only the 292 is unique. Watch the video again and I explain the difference between a 250 and 292.

[@eperjesirama]

Great content! Do you have any recommendations on roller rockers?

[@SquaredAwayGarage]

I would recommend speaking with the manufacturer of the cam you decide on. Pretty sure all the companies that make roller cams for these engines also have roller rockers .

[@zAvAvAz]

How much does a 292 weigh versus a 250 or other?

[@SquaredAwayGarage]

Unfortunately I don't know the answer to that. Just guessing, I doubt there is even 50 lbs of additional metal in a 292.

[@douglasames6495]

Total confusion ?? Where do you get a frame stand for a 292/square body combo?

[@SquaredAwayGarage]

I got mine from a salvage yard. Ebay is a good place to shop sometimes also. I've found the most common truck to get them from are the C20's. If you're buying an engine from someone who is pulling it for a V8 you should get the stands and mounts when you get the engine. Even if it is from a different generation of truck. You may be able to trade with someone who has what you need and needs what you have.

[@katskratchkustumz]

fab one up

[@charlescox6608]

That's because the 292 has an extra main bearing !!!!

[@SquaredAwayGarage]

It has 7, just like the 250 or 230.

[@user-sc1ck6ec8f]

Just because it's Chevy doesn't mean there all the same

[@SquaredAwayGarage]

But there aren't multiple configurations of the 292 engine block. They are all the same and have an offset motor mount on the passenger side.

[@user-sc1ck6ec8f]

You have considered some of these came from Canada not all are from u.s little things are different! My buddy didn't believe me when I saw a 1964 GMC with trailing arms how I knew for a fact GMC ONLY DANA AND IT DID NOT FIT CHEVY

[@SquaredAwayGarage]

GMC and Chevy products were definitely different back then. But if you had a GMC with a 292 engine in it, it would have had 292 specific frame stands.

[@user-sc1ck6ec8f]

@@SquaredAwayGarage maybe special order who knows the 62 Chevy was the only that was a little bit of a hassle putting 89 suburban cross member disc brake swap frame is boxed in the front and had to drill holes for the 292 mounts on frame because that year had the motor mount under the harmonic balance for the V8 265 and 292 6

[@user-pq3bz2jh8l]

If you are going from a 250 to a 292 in like a chevy 2. The 292 may have hpod clearance problems ? Engine is several inches taller

[@SquaredAwayGarage]

I'm not exactly sure how much taller the 292 is. I should measure that someday. But yes the 292 is taller by about and an inch and a half or so. I've never tried to do a swap into a car,but I've heard it can be done. I assume some cars will accommodate the 292 better then others, but can't really help you determine if what you ha e is one of them. It may require some modifications somewhere to make it fit.
