I have a 63 Chevy II race car with a 292 and previously had 66 street car also with a 292.
The left motor mount from the 194 will work perfectly as is. The right side you will either need to modify the mount or the subframe adapter due to the rearward location of the 292 mount. I went to electric fuel pumps on both cars. On the 66, we used a 250 Chevy II pan (center sump) and needed to shim the motor up ~ 1/8" to clear the steering linkage. It may have been due to having dropped spindles, but I am not sure.
The race car has a truck rear sump pan and clears everything.
If you use a stock two groove balancer you should be ok length wise. I used a Fluid Dampner on the 66 and ended up with two small electric fans, one push and one pull due to clearance issues.
On the 63, cut the core support to put a big radiator in.
With a 2X4 Clifford manifold, we needed to cut and weld the adapters to the manifold so there would be enough clearance for the stock hood. With a 1x4 Clifford manifold it worked with a very thin air filter with no mods. Used Edelbrock 600's on both combinations.
Depending on mods to the motor, which tranny you are using and rear gears, the 3000 stall may or may not work. For a point of reference, my 66 had minor head work, a Clifford 264H cam, ~ 9:1 compression, a 700R4
(3.06 1st gear) and 4:10 rear and worked really well with a 2600 stall. It actually stalled at ~2300-2400.
There is always debate on the 194 vs the larger heads. If you do not want to do a lot of head work, you will probably be better off cutting the stock head to gain compression due to its better, at least stock, flow characteristics.
Good luck on the project.
