Is there any difference between a 1952 1/2 ton GMC chassis and a 1951 1/2 ton Chevy chassis. I have a '52 Gmc chassis with the 228 and trans available to me to replace my rusted one.Is the 228 the same engine size as the 216, or are there some distinct differences ? I think my 216 is fine for now but it is always nice think you have a spare engine. Thanks for any info.

Many people will tell you that the GMC's are superior and in some ways I guess they are. The 228 GMC was purposely designed as a truck engine. It has full oil pressure to the insert rod bearings, heavier, beefier rods and a higher nickle content in the block. The GMC boys can list more things that make it better. The 216 is a car engine, though it made its way into millions of Chevy trucks and I love mine. Have you checked out oldgmctrucks.com? Lots of great info over there and an active forum. You can probably put your 51 Chevy cab/body on the GMC chassis. The radiator will probably have to go forward approx 1-2". Maybe Oldsub or one of the other GMC knowledgeables will chime in. Good Luck!!

That front crossmember is the only real difference between a Chevy and GMC frame. The crossmember is different in several ways that might matter to you.
1) The motor mount is further forward to support the longer GMC motor.
2) Because the motor is longer, the radiator is mounted further forward, and its supported by this crossmember. Since all the front sheet metal mounts off the radiator mount it affects all that stuff.
3) There are original factory sway bars available and since they mount on this crossmember, you must use a Chevy on a Chevy or a GMC on a GMC, though I suppose some creative work might adapt one...
It would take removing a bunch of rivets to swap crossmembers, but I'm sure it can be done.
As for the motors, the GMC is all of the things mentioned above. But the larger 270 and 302 are the only ones considered desireable, the smaller 228 and 248 seem only of interest to serious restorers.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
