Decoding my 65 vin

[Budman56]

CAN ANYONE HELP WITH DECODING MY 65 C20 VIN, THIS WEBSITE DECODING DOESNT WORK FOR MY 65 VIN, AND OTHER SITE I HAVE BEEN TO, DO NOT DECODE THE 65 EITHER. ALSO THE UPPER CORNER OF THE VIN SHOW CHEVEROLET DD WHAT IS THE DD

I'll take a stab,,,
C= Conventional (2WD)
25= 3/4-Ton
4= Pickup
5= 1965
Z= Fremont assy plant
153451= Sequential Serial number

DD probably stands for Delivery Date. The dealer could stamp this space if he wanted to with the date the truck arrived on the lot. Not many did.

C 254 52153451 reads as follows C= 2wd 25= 3/4 ton longbed 127" wheelbase 4=pickup 5=1965 Z=Freemont assembly plant 153451 =53451th unit built Each year begins with serial number 100,001

the 1965 engine options that im aware of for the c-10,k-10, c-20. k-20 were the 230 w/date codes TA, TE, TG 292 w/date codes UH, UT 283 w/date codes WA, WE. Ive heard of some late models that had 250, but not sure if factory...I know it was a 1966 option as was the 327.

What engine do you have now? If its a 6cyl, the stamp will be on a pad next to the distributor and if the v8 it will be forward of the right side cylinder head

what I have now is a V8 327 which I dont think was an option for this year truck. I was wondering if there were something in the vin or some where else to tell me what the truck should have came with.

The L6 to V8 conversion is fairly simple, so either could have come with the truck. What does your upper radiator mount look like? If its flat, most likely it came with a 6, if its raised most likely an 8

There is nothing on the truck or VIN that will tell you what it came with. Rarely...you can find a factory build sheet on the underside of the seat. I would start with running the numbers on the block that you have. Im more familiar with the 60-63 models...so maybe somebody can pipe in, but sometimes towards the end of a model you will find the next year engines. The 327 was listed for the 1966 models, but was made from 1962-1969 and the 283 from 1957-1967.
