I have what i belive to be a 69 390 Iam trouble finding the block numbers. The only numbers I could find were just below the oil filter housing. Shows W1 8k26. On the heads I found C8AE-H.
Are thease the right numbers and what do they mean?
Thanks
Dave

Dave,
The 8K26 is the date code of the block. I think it means Nov 26, 1968. Sounds like the engine could be original. You will also find a simular number on each head and the intake. Do you know if the engine is suppose to be original to the truck?
The block number may not really tell you much. Are you positive the engine is a 390? I went for almost 2 years thinking I had a 390 when in fact I had a bored 360. Measure your stroke if your not sure. Also check your VIN. Report back and tell us what the 4th character is if you are not sure how to decode it.
Good luck,
Lee

For Lee, I noticed that by your post here that you mentioned you could decipher the vin for an engine size. I have a 72 7000 dump with what I believe is a 391, is that number decipherable as well?
The plate on the door has the following info:
N70 EVN 50368 (the VIN)
220 6 N709 4AB N E23
19200 182 3800 28
I haven't any idea what any of it means, except maybe the 19200 is the rear axle rating. Could you help me with this?
Thanks in advance
Bob

[updated:LAST EDITED ON 01-12-03 AT 07:31 PM (EST)]I put info in a VIN decoder. It came back as a 300-6 w/ single barrel carb. Said was assembled in Kentuky.
I doubt that this info is acctually right. The decoder is for a f-100-350 and bronco's. But, I figured I would give it a try.
The N70 stats it is a 7000 series truck. the E or 4th letter of vin tells what the engine is. 5th letter tells assymbly plant. I think 6th letter is also part of the assembly plant maybe the line it was on. The rest are the consecutive unit #.
Hope this helps.

I believe that it an original 390 or so Iam hopeing, the engine ran when I took it out did not want to take it apart just yet. Only things I could find on the door was the following
F25HRE28839 now it said this was a warrenty # is that another way of saying vin #?
WB 131 COLOUR P MODEL F254 BODY M 81 TRANS 6 AXEL 38 GVW 6900 HP NET 185 RPM 4000 A7 DSO
Most of this i can figure out but whats the axel code and the HP net mean is that 185 HP at the wheels? oh and the A7 DSO ?
I have painted the block and I can not for the life of me find the block numbers anyone have a picture of where on the block to look? I did find 352 28 cast on the front.
Thanks for the help you guys rule
Dave

Hey Scotty, I'm sure there must be some confusion in that system. The truck is (likely) a 391 w/ 4 barrel, a 5 speed Clark trans, 2 spd rear axle (maybe the 19200 is the GVW, I thought the rear wt. rating?)
I appreciate your efforts though. I saw the VIN decoder also, but since it said nothing about BIG trucks I didn't even try it.
Maybe someone else has access to a decoder for something like this.

Bob,
I am not sure how correct this info will be as I am taking it from a 1970 manual. Anyway, here goes.
N70(truck series code, N = Conventional 2-axle gas)
E(engine code= 361-2v)
V(Assembly plant code, V= Kentucky Truck)
N50368(Consecutive unit number)
220(Wheel base)
6(Exterior paint code, 6= Med. Blue Metallic)
N709(Model code, not listed in my book)
4AB(4= Cab trim, Black; A= Seat type, HD blk vinyl full seat; B= body code)
N(Transmission code, N= 5-speed Spicer 6352 Direct)
E23(Rear axle code, Eaton 16244 5.57/7.75, 2-speed, 17,500lbs)
19200(Max gross vehicle weight)
182(Certified net HP)
3800(Specified RPM)
28(DSO code, District Special Order code, 28= Louisville)
Does any of this sound right for your truck?
Lee

Dave,
Yes, the Warrenty number is the same as the VIN.
This is how my 1970 manual breaks down your numbers: F25HRE28839
F25(truck series code, F= Conventional 2-axle gas)
H(engine code= 390-2v)
R(Assembly plant code, R= Lorain)
E28839(Consecutive unit number)
131(Wheel base)
P(Exterior paint code, P= Med. Ivy Green)
F254(Model code, = F250, 6900 GVW)
M81(Body code, not found in my book)
6(Transmission code, Could this be a "G", if so = Automatic)
38(Rear axle code, Dana 60, 3.73:1, 5200lbs)
6900(Max gross vehicle weight)
185(Certified net HP)
4000(Specified RPM)
A7(DSO code, District Special Order code, A7= Pacific Mercury Region)
Most block numbers are located on the passenger side of the block either behind the alternator or back beside the starter. Don't be surprised though if your's does not have ANY numbers. As I understand it this is not too uncommon.
Hope this helps,
Lee

HP was never taken at the wheels. Gross means how much power the engine made on the stand with no alternator, power steering, air conditioning or anything else. Net is on the stand with all accessories attached.

Thank you Lee, some of it does look reasonable, some might not. Guess I'll pull a plug to measure the stroke, as I was thinking it was probably a 391 due to the 4 barrel carb. But heck they look the same, LOL.
It may be a spicer trans as well, I REALLY need for it to warm up a little to get some of that gunk off of everything to find some tags.
I really do appreciate your efforts, and hope maybe I can repay you in kind.
