ok know I need to know what is different on the 292 then on the 250 what will inter change between them. I know the head is the same, I think. I know you can use a 250 cam in the 292 if you don't needed the fuel pump cam. I know the motor mounts are in different places on the 292 then on the 250. what parts inside can be use between the two. Thanks guys

292 rods are longer, cranks are different, I think pistons are different. Pushrods are longer. Lifters should be the same. Oil pump is the same.

Engine is a bit taller which accounts for what GMCpanel sez. So the push rod covers are also bigger.

you are correct as to not swap cams cause the fuel pump is located in a different area. 292's between #3 & 4 cylinders. heads yes - 192 heads are 57cc, rods no, harmonic balancer no, water pump puts out more volumn on 292 and can be swapped. The 292 is 1.75'' taller. The side pushrod covers are 2 piece & 6'' on 292. The valve train is different between the L6 and V8's even though the specs are close.

All L22 side covers are two-piece. The 194/230/250 covers are obviously shorter. You can use a 194/230/250 cam in a 292 or vice-versa with no problem if you use an electric fuel pump.

I didn't mention the block height because I thought it was obvious.
