| | THANKS!
For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Oct 2015 Posts: 4 New Guy | | New Guy Joined: Oct 2015 Posts: 4 | I'm looking at buying this truck. From the title it says it's a 1956 Chevy 6400. The VIN #V6B56S024625. I don't know all the lingo used to classify these things. I want to know what size it is (2ton?), and if I'm wasting my time starting a project with this truck. Its in good shape. Runs and drives fine. One owner truck. I'm wanting to bag it and do a diesel swap. Preferably Cummins. Any input would help. | | | | | Joined: Mar 2000 Posts: 1,177 Red dot, center of chest ... | | Red dot, center of chest ...

I my experience driving and using the truck like it is for a good while gives a much better perspective on what is important to you and what might be necessary, and likewise, not necessary.

I figured the information was somewhere buried in this site but when you're new to it it's a bit overwhelming. I know for sure I want to bag it and do a 12v Cummins swap. I've had a few people say to just buy a dodge dually and put the 56 cab on the dually frame, but then its not the same. I want the original truck. That's what makes it different. I just assumed there were a few guys in here that would know whether or not this model would be a good platform to start with. Thanks again guys. | | | | | Joined: Mar 2004 Posts: 6,214 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,214 | I can't help with the diesel swap other than to say, get the tape measure out and see if the Cummins will fit. Is the existing motor a 6 or 8 cylinder? Mike B

If your truck has a dump you will need to locate a pto output trans. Good luck and keep us posted | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | Dropping it, bagging it, doing a diesel swap ! It's never going to be original again after that, so why not put it on a later chassis. A lot less work. It's going to be a non original custom, either way you put it. | | | | | Joined: Oct 2015 Posts: 4 New Guy | | New Guy Joined: Oct 2015 Posts: 4 | Thanks for all the input guys. The original engine is a V8. I think it's commonly referred to as an RPO or something like that. I may be completely off. Of course the truck won't be original after its chopped, bagged, and blowing black smoke, but I'm not wanting original. I want all the original body and frame. There is tons of 3/4 ton dually framed bagged trucks out there so that wouldn't really turn any heads. I haven't seen many in the "big bolt" format! Haha. That name alone is just cool to me. But thanks again. You guys have been a lot of help. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Oct 2015 Posts: 4 New Guy | | New Guy Joined: Oct 2015 Posts: 4 | | | |
