292 motor mount bracket

[l79m20]

I know that the perch for the passenger side motor mount must be the one used for the 292 and must be moved forward a bit. I have done this in the past but today while getting ready to install the 292, the motor mount bracket that mounts to the block will not fit . I am attempting to use the brackets from the previous motor a 250. Does the passenger side bracket from an original 292 have to be used also? Thoughts

292 pass side perch is only for a 292. nothing else works

I know the perch is but what about motor mount bracket to block?

[padresag]

they are all the same

There are spacers between the block and mount, also think the mount it's self is different.

I ran into this the other day myself; I was trying to use '69 250 block mounts on my '73 or '83 292 block (IIRC). Not sure how it varies through the years (or if it does).

I decided that it seemed like I could redrill the mount and make it work IIRC, but I need to pull the correct mount off another 292 I have and check (hopefully Sunday/Monday).

Anyone else?

See above.

the subject is 1963-6. as also above I said that the 292 pass side perch is it's own. the ones between the block and the insulator are the same

I am not talking about the 63-66 right hand perch that mounts to the frame, we all know that the 292 uses its own.

The right hand block mount that goes between the block and the rubber mount that came off my '69 250 is absolutely not the same as what is on my other 292 and will not work on my rebuilt 292 that needs the same mount. I'm not sure about early blocks, but the statement that "the ones between the block and the insulator are the same" is wrong. There is absolutely a 292-specific right hand block mount (at least for the later model blocks).

but we were. you were the one that brought in the other
it is the perch that is specific in these years

Okay first is 230,250 second is the factory spacers on the 292 third is 292 block mount which is different from the 230,250.hope your happy this was driving me nuts so I went out to my shop in my boxers to figure this out at 12 am.

I'm not sure where the confusion is. The OP and me both have 63-66 trucks with the correct 292 frame mounts. The left side block mount bolts on the block fine, the right side does not and is different. My '63 with a 292 has the correct mounts on the block and the right side is absolutely not the same as the left and will not interchange.

The only reason I add the disclaimer that both mine are not 63-66 blocks is because I am unsure if those are different, since I don't have one.

It's obviously not. Like I said, I'll try to figure it out Monday and get some pictures for you.

Interesting. What era is that block? IIRC the bolt pattern was also wrong on mine. Not sure what the deal on my other 292 is, but it doesn't have spacers in between the mount and the block.

[hotrod66]

Not shure it's a target block made in Mexico but I took both the mounts from my factory 292 that was in my 65. previously the engine was in a 76 6x6 one ton guess I got lucky with mine.

The mount brackets should be the same for all 6 cylinders and sbc's in the 63-66 era as all those years had the option for the 292. The perches I thought were the same to. Only difference I new of was where they mount. The 194-230-230 mount different on the passenger side vs the 292. The small 6's mount in the middle of the block and the 292 further up front directly behind the dizzy. Its to early in the morning for me....I'll be back later.

??? A SBC does not use the block mounts, the rubber mounts are bolted directly to the block itself.

The right hand 292 perch is not the same as one for a SBC or smaller six: http://www.persh.org/pickup/perches.htm

My 292 block is of 1971 vintage, so I guess i'm looking for a later model bracket to block for/off 292. Thanks for everyone help.. Are the 292 dipsticks different also?

[66Submarine]

Another thread I found discussing this: http://67-72chevytrucks.com/vboard/s...=493950&page=2

[66Submarine]

Ok, I did some more research and managed to find some pictures I took.

Apparently the 230/250 right hand side mount is the one that is different. It appears you need two left hand mounts with spacers on the right hand one to make the 292 setup.

I'll do some more checking when I have the stuff in my hand and report back...

I agree you need 2 of the left hand mounts and spacers for the one you put on the right side.

I guess what You call mounts and what I call mounts are different. lol

To clarify, this thread is about the part that bolts to the engine block that the rubber isolators/mounts bolt to, which I am calling "block mounts". A SBC/BBC does not have them and the rubber isolators/mounts bolt directly to the block itself. I am referring to the part that bolts to the frame that the rubber isolator/mount bolts to as a "perch", which is how I've heard others refer to them.

Hey thanks everyone, Found a pair of left side brackets in a box along with one spacer so am down to finding one spacer to finish 292 install. This is one outstanding forum, thank you all for your input. Anyone know where I might find one spacer?
