Need advice about keeping original motor and transmission

[Old&Slow]

The wife and I are in the process of retro-modding a 59 GMC that her father had since the early 70’s. It has lots of sentimental value to her since she grew up with the truck in the family and even more after her father passed away about 10 years ago. Her father would garage the truck during the winter and it was kept in the garage since he passed away.

We are setting it up as a reliable casual driver with the potential to tow a retro camper. We are installing a V8, auto trans, power steering, power disc brakes, etc. and have decide to replace the frame instead of cutting up and welding the old one. Which brings me to my question. It has the original matching numbers engine and transmission on the original frame. I was planning on storing these parts but the possibility of us converting the truck back to its original state is probably never going to happen. I was hoping someone could convince me to sell the rolling frame with the motor and transmission, instead of me storing it and never using the parts. I don’t think a matching engine and transmission, even on the original frame, have much value without the body, but would welcome any advice.

Thanks, Pete

P.S. This site has been great for restoration information, really happy I found it!
