I pulled the carpet that the previous owner put in. It had a fiber backing that just holds water so I am down to bare metal floor now. I can can keep an eye on it anyhow. I did a temp fix on the throttle linkage. The pedal was sticking in the down position. The pivot where the pedal linkage, and the linkage to the carb connect was stuck tight. I could hardly get my hand on it though. I can't believe that linkage is so hard to get to. You almost have to pull the exhaust pipe to get to it. Anyhow, I loosened the stud just enough to let it release. The pivot isn't moving, but the bolt is. While I was snooping around I located the casting number on the engine, not far from the carb. It was 3836848 and had GM 6. As far as I can decifer on a number search, is that engine is not origianl and is a newer, 1956, 235 engine. Is that right?

I have the same number on the engine in my 54. has the oil gauge been upgraded to 60 lbs as well or does it still show 30 lbs? The inliners site has some good info as well as the vin decoder on this site. you should also have a stamped number on the block just behind the distrbutor above the starter. | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | Casting No., on the block, is located on the passenger side forward, of the starter. | | | | | Joined: Sep 2006 Posts: 1,997 Big Bolt Forum Co-moderator | | Big Bolt Forum Co-moderator Joined: Sep 2006 Posts: 1,997 | The block casting number looks like D 166, it is right above the starter. Between the starter and the distributer, on a machined surface the following numbers are stamped, 0910182 F55P3.Does this jive with the head number of 3836848. The oil pressure gauge is 30 lbs.

It does not look correct, the first number would be 3.
Often times on casting numbers it is hard to tell a 3 from and 8 or a 2 might appear as a 7.
Try to rub the number off with a steel brush and see what you come up with.
Let me know and I will decode it for you.

F = Flint engine plant (T = Tonawanda plant). 55 = year 1955 P3 = ??? P3 doesn't show as a good code...need help, check numbers again. D 166 sounds like the cast date code. D = April 16 = Day 6 = year (1956) Could this be a dealer replacement done under warranty? The engine serial numbers we used for title purposes back then and the dealer may have transfered the original numbers to the replacement block to keep things correct for the owner. Do the number look hand stamped (not quite straingt or spacing off a little) or machine (everything in line and even)? Is this number on your title?

Bill | | | | | Joined: Sep 2006 Posts: 1,997 Big Bolt Forum Co-moderator | | Big Bolt Forum Co-moderator Joined: Sep 2006 Posts: 1,997 | So, Is the 235 a babbited engine? The truck is only suppose to have 34,000 miles on it. Wonder why it would have a replaced engine? Me thinks I have been too trusting. Well, at least I am getting to know the beast a little better. I don't think I'll be buying anything too big off of ebay again. Everything gets too rushed.

I don't know how many people actually followed OEM maintenance schedules. My 38 owners manuel recommends 1000 mile oil changes and pulling wheel bearings evry5000 miles if i rememmber correctly. I'm glad oil and greases have been greatly improved | | |
