292 into 68 K10

[RichardJ]

Don't know if a 250 pan will fit under a 292, but as far as I know the 292 pans were 6 qt. A 250, if it would fit, might need a different dip stick and tube. I don't know.

Twisted 6 plays with Chevy II's, so it would explain why he might have sent you a center sump pan. The Chevy II had rear steer with tie rods and drag link behind the axle center-line and behind the sump. Chevy II inline engines had the dip stick tube nearer the front of the block, next to the fuel pump. Early Chevy II V8 engines had a front sump with dip stick on the other side.

Could be why.
I wouldn't want to run a 250 pan on a 292 even if the bolt pattern is the same. Six quarts aid engine cooling and that's a big plus in the Desert.

The pan off the original 250 in my 68 K10 will not fit on the 292 because it's not deep enough at the front to clear the counter weights.The 292 is an early engine with a forged crank, maybe the cast cranks have different shaped counter weights or other 250 pans are deeper in the front? If not it's a situation where they are all the same except for the ones that don't fit ,lol

After chasing down false leads for a cross member I built one. Cut the lower hoop out of the stock cross member and bent a length of 3/8 thick steel to fit.. I mocked it up on the engine while it was on the stand..Then bolted it in and made some slight adjustments. I welded the small patch on the right frame rail to repair a very thin area from local corrosion...The rest of the frame is clean...

Those later cranks had 12 counter weights, as opposed to the 6 on the earlier cranks. I think that the cross member to put a 292 in a K is about the most specific part made for these trucks. That's why I'm keeping a hold of the one have, too!

The early 6-lobed cranks can be knife-edged so they slip thru the oilbath with less resistance. Old school trick, that I'm not sure has any added benefit, but it sounds cool.

The engine dropped in and positioned properly on the modified 250 mounts... The 292 is slightly modified with 9-1 compression and a mild Schneider cam.

I am curious, which Schneider cam? Stock I believe is 188/188. I have the 194/204 and Schneider has two others that are only slightly bigger.

194/204.....The stock cam was trashed and I was looking for a slight increase in usable power. I found a good deal on new 9.3 compression LP pistons. I cc'd the heads and piston depression, head gasket thickness and the actual compression 8.95 with the block decked .025 to get a reasonable quench.
Jerry at Schneider told me their 194/204 cam was used as a replacement cam for stock rebuilds by fleet truck operators.
