GMC engine in a Chevy
Ok, I have a 1954 Chevy pickup it has a 1954 GMC Cab and a 248 GMC Engine. I know the front cross member and radiator support is not the same . The 248 GMC Engine is a few inches longer. The front motor mount has been modified. I am now at the point of installing the radiator. My questions is , has anybody on this forum installed a 1954 GMC engine into a 1954 Chevy Pickup? I could use some tips on installing the radiator. Thanks

Re: GMC engine in a Chevy
I'm not for sure what's all involved. According to this article, you can use a 235 crank pulley/balancer and then modify your water pump pulley.
I do know that on the 235 water pumps, you can press the pulley mounting hub down shorter. That's how the long water pup 235's are modified for the early trucks. http://www.chevytrucks.org/tech/gmc302.htm Looking at my Chevy, you can probably move the radiator to the front side of the support. You may have to do some trimming to the upper suppprt though. My dad had a GMC powered 3100 back in the 70's and they also put a GMC in one of my grandpa's grain trucks. He doesn't remember how they did it. With him, I'm sure the hot wrench was involved. Last edited by whitedog76; 03-25-2014 at 10:06 AM. |

Re: GMC engine in a Chevy
Does your front crossmember look like this:
 which is a GMC crossmember or does it look like this Chevrolet crossmember?  I'm trying to figure out if you have a GMC engine, cab and box on a Chevy frame or someone has swapped a Chevy nose to a GMC and used a Chevy title with it.

Re: GMC engine in a Chevy
Thanks everybody of the information. And a special thanks to Whitedog for the article, it gives me a better idea of what I am up against . I know it will be a good running GMC/Chevy when I am done. Thanks again.
