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: Aug 2004 Posts: 17 Junior Member | | Junior Member Joined: Aug 2004 Posts: 17 | I picked up a 49 chevy 6400 flatbed a week or so ago. I have not been able to look it over real good because I work on a remote island in alaska. I have found vin number info. but have been trying to determine what type of engine I have in it. the wife got the s/n number next to the distributer, it is 0668479F54Y, I am having her look for casting numbers off the block, and she has not found them yet. she found the casting numbers of the head 3701887. the little I have found it looks like this engine might be a rebuild of a couple differant years. Can anyone help me confirm this? | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | The "F54Y" indicates that you have a 1954 235ci inline 6, a good year most would say, due to the pressurized lubrication system. That's what my book says, Scott | | | | | Joined: Aug 2004 Posts: 17 Junior Member | | Junior Member Joined: Aug 2004 Posts: 17 | Originally posted by dhook: I picked up a 49 chevy 6400 flatbed a week or so ago.

Also the head casting number seems to have come off a 53. Is there anything I might need to know about this combanation, Parts, valve adjusting, ect.?
thanks for the reply. | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | My book doesn't list the casting numbers, just the stamped "I.D." numbers from the factory. There are many fellow bolters that have this info and I'm sure they will be along shortly. As far as your parts compatability, I've never done the mix-n-match thing with the inlines before, so I can't help you there either. There will be someone that has along soon I'm sure. Good luck with your fine truck, Scott | | | | | Joined: Aug 2004 Posts: 17 Junior Member | | Junior Member Joined: Aug 2004 Posts: 17 | Thanks Scot,
Its looking like a mix and match so far, not being there to confirm all the numbers myself makes it diffacult. I'll wait to here form some others. | | | | | Joined: Aug 2004 Posts: 17 Junior Member | | Junior Member Joined: Aug 2004 Posts: 17 | Thanks, I've been to two of the three site's, the third will help.
