| | 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: Mar 2009 Posts: 17 Apprentice | | Apprentice Joined: Mar 2009 Posts: 17 | I recently bought a '49 3600, with original parts, including the engine. The engine has the (apparently common) 'babbit rod knock' and recently started burning oil.
I'm a newbie, not mechanically savvy, and am torn between replacing it with a 235 or having it rebuilt.
The engine only has 43,000 miles on it and the rest of the truck is in very good shape. I'm weighing the pro's and con's of a 'numbers matching' truck with a stronger/more reliable engine. Any advice?
Lastly, what would one expect to pay for a good rebuild of the 216 or for a reliable (rebuilt) 235? Is there a significant value difference for 'numbers matching' if I restore the truck? Thank you in advance for any help.

Burning oil could be something as simple as valve seals or more severe like broken piston rings. Check the compression on all cylinders first and see how even they match to each cylinder. You may just need the cylinder head reconditioned. That price can vary between machine shops, but could be several hundred bucks, but way cheaper then a complete engine rebuild.

Getting ready to begin putting my 235 together that I swapped for the original 216 babitt poured bearing smoker beast. Drank more oil than the gas it used. My cost including new crank, pistons, cam and machine shop work is right @ $2500.00. If you are going to make a trailer queen show piece out of it to sell then worry about #'s matching. It's a truck not a 'Vette...I want to drive it, heck I want to drive that 'Vette too!

I don't think "numbers matching" is something that is considered with these AD trucks. With auctions like Barrett Jackson, the upgrade seems to bring more money than the original. | | | | | Joined: May 2009 Posts: 181 'Bolter | | 'Bolter Joined: May 2009 Posts: 181 | are you sure the odometer hasn't rolled over? maybe 143,000?
I love the idea of keeping and original truck original....but it does take some coin.

I'll determine if a modest investment will get the 216 running 'smoke free' - if not I'll find a solid 235.
Thanks again.
