292 into 68 K10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tony · 10-20-2015, 11:42 AM

I'm about to pull the 250 and replace it with a 292. I have to deal with the right side motor mount. I can fabricate whatever is needed but a photo of a factory 292 installation would be helpful.
Show me yours ,Thanks

**slomotion** · 10-20-2015, 02:24 PM

Tony, see if these help.....

Tony · 10-20-2015, 03:09 PM

Thanks, the 4x4 has a different cross member but the general layout is the same...

Tony · 10-21-2015, 05:20 PM

More issues...The 292 oil pan I have won't clear the bolted in cross member....The 250 oil pan won't clear the 292 crankshaft... Time to fabricate what I need...

**slomotion** · 10-21-2015, 05:59 PM

Maybe there's an after-market pan that will do the trick. Surely there were 292's in the "K" series trucks...........

Yes....The cross member and oil pan might be different....The cross member can be massaged a bit but clearance on the right side is tight because of the differential. jacking up the engine a touch can help...

Off topic a bit but will a 292 fit into a Custom 10 (1972) that came factory with a 250?

I wondered about jacking the engine up a little but didn't know if that would cause issues with the tranny/floor pan clearance or drive shaft angle.

There's enough room to lift the engine about 1/2 inch... I have a 1971 GM truck master parts manual. 63-70 series 10-30 292 oil pan part number is different than the 230-250 .No mention of two or four wheel drive pans. The frame mounts have different part numbers for the various engines and or two or four wheel drive

Yes,try and get a photo of the motor mount cross member, Thanks

**CanadianK10** · 10-23-2015, 09:36 AM

Hope this helps

Tony · 10-23-2015, 12:28 PM

Well, that explains a lot.....different shaped cross member and angled to fit the more forward right side mount... Thanks

**slomotion** · 10-23-2015, 12:46 PM

Is the cross member as close to the pan as it looks, or is that just camera angle?
Just curious.

**CanadianK10** · 10-23-2015, 02:26 PM

Theres a bit of room but not much. Was a pain to try and paint in there, had limited successs.

**'68OrangeSunshine** · 10-23-2015, 08:10 PM

I have a 292-only 4x4 crossmember. Trying to pull up old pics.
Here ya go:
They have a diagonal orientation.

Tony · 10-24-2015, 07:24 AM

Exactly what I need...send em my way,I have money

**'68OrangeSunshine** · 10-24-2015, 01:40 PM

Sorry. I should have stated in my post that they were not for sale. I only showed them so you'd know what they look like.
Keep a lookout for post where some kid is dropping a 292 to put a 350 in. [They're usually pretty gullible.] Talk them out of any L6 related parts they won't need in their 'brilliant' move to V8 Land.

Tony · 10-25-2015, 03:40 PM

Today I mocked up the cross member on the 292...Using the 250 left engine mount bracket and the 292 right side...The cross member is not as close to the pan as it looks on this Iphone pic.
I just going to weld flat stock to the cross member mounting bracket to support the engine mount. Then a bolt on gusset for added strength and call it good...I've done many engine swaps and it'll be fine.If it ain't ,just fix it more

The cross member just misses the pan corners.. Jack up the engine about 3/8 inch ,should be ok.
The oil pan is a mess of brazed repairs so I got another one coming.

There's an Early and a Late configuration on 292 oil pans. Not sure of the actual time line, but '63/'64 oilpans had a 'midships' sump, The Late ['67/'68] pans had the sump aft.
Don't know where '65/'66 would fall.

Tony · 10-25-2015, 07:21 PM

The pan came on the the engine in the photo, casting date F164

And is the sump in the middle? If it's a fitment issue, a '67 oil pan might work better.

Tony · 10-25-2015, 07:28 PM

292 oil pans in good shape are not easy to find....I would call the pan on the engine a rear sump...

**'68OrangeSunshine** · 10-25-2015, 07:37 PM

I bought one from Larry Page [Twisted 6] about 10 years ago. Turned out to be an Early style.

Tony · 10-26-2015, 07:33 AM

I believe some 250 pans will fit a 292, mine wouldn't. But the front of the a 250 ,if it clears the crank, is too shallow and the oil will be churned up more than it needs to be...
