I'm a bit confused. A 292 is a Chevrolet truck engine. A 1952 GMC is a truck. A 1950 Chevy chassis is a car chassis.
Are you wanting to put a GMC truck engine in a car or a Chevrolet truck 292 engine in a car?
Or, is the 50 Chevy chassis a 1950 Chevrolet truck chassis?
Or/and, is the 50 Chevy chassis a 1950 Chevrolet truck chassis upon which will be a Chevrolet 292 engine upon which will sit a 1952 GMC truck body?
The front crossmember supports the radiator yoke which holds the radiator.
The yoke is the "anchor" for the front clip (fenders, inner fenders, hood, etc.).
If you relocate the crossmember and/or the yoke, you bring on many headaches (alignment issues) later.
You can move the radiator itself (brackets etc.) forward for clearance issues.
The front crossmember is riveted-in. For safety, it is important that it be in good condition and not modified.
The 292 is a side mount engine. You can use/modify V8 mounts (I recall that the 292 mounts are staggered, one higher than other, please check).
You didn't mention what drivetrain you have and if the rear axle angle is correct.
Also, the 292 is a 12 volt engine and a 1952 GMC is 6 volt. The 292 will have a starter solenoid versus the older foot starter.
The 1952 GMC will have mechanical oil pressure and water temperature gauges (a fragile Bourdon tube). Adapt and reuse or buy new gauges for the 292.
