WIW: Pontiac 336 and transmission

[58-GMC]

I am in the beginning stages of the build on my 58 GMC and my plans do not include the original engine and transmission so I am looking for some guidance from you guys on what everyone thinks is a fair asking price.

It’s a Pontiac 336 V8 and manual transmission that is currently in running order.

Don’t know a ton about it as this truck was my dad’s. He was in the middle of restoring it but unfortunately passed away from cancer four years ago. A couple years ago I had a buddy who owns an engine shop look over the engine and transmission to ensure it had no major issues before I moved it out of my dad’s shop and over to my garage.

Here are a couple pics of the engine. The darker spots are dirt and wipes off pretty easily...it's just cold here in MN so I didnt want to bother cleaning it for the pics.








I would also like to hear what you guys think I could get for the entire long bed chassis, suspension, engine, and transmission, etc…basically everything except the body components (cab/bed).

Since my build includes an LQ4/4l80 swap, full Porterbuilt suspension, and shortening of the frame and bed, I thought it may be a better route to sell the complete long bed frame and grab a short frame. I know a guy who has a 58-59 frame and he’s offered to install the Porterbuilt suspension. He isn’t local to me but has installed many of these kits and is well known for his work so I know it would come out top-notch.

This is my first build so I appreciate any feedback and pointers you guys have!
