Build Dates

[William L.]

I have a friend that bought a 67 coupe that had an amature body off restortion done to it a couple of years ago. We were wondering how close can the dates be and still be acceptable? The dates are as follows.

block casting # 3892657 Date C317 (Mar 31 1967)

Engine stamp date V0403HT (APR/03/350HP) Has nice broach marks.

Body build date H28 (MAR 28) A.O.Smith body # A-1353

By the vin# cars approximent birthday is 8 APR 1967 (That's a Saturday?)

Most all of the other part numbers are dated FEB & Mar.

This car is very nice and seems to be very correct. What's your thoughts???
Thanks
Bill

Re: Build Dates

Dates all sound like they line up to me. The 8 Apr 1967 for a birthday you have to remember is only an approximation. The accuracy is first dependent on the calculator and second on how "normal" the shifts ran that month.

I have a Bowtie 67, built late March with a born on date about April 1. All the dates are very close together, most are within a few days. March was one of the highest monthly production totals for the 67 model year, thing were getting in and out quite rapidly.

Re: Build Dates

With relation to the build dates, how far apart can they be? Example..I am looking at a 69 BB with a castin date J188(Oct 18 68) and a engine pad date od TO4O2IL with corresponding serial number. Can there be that much of a gap between casting date and build date on a 512 block? Thanks

Re: Build Dates

Thanks guys for you response. I guess its not unusal to see the dates that close together! Thanks again Bill

Re: Build Dates

While NCRS allows 6 months, I'd be looking very hard at that. I have seen engines that are several months before the car's date, but usually the casting and assembly dates are within a few days to a week or so at most of each other.

Basically, where would that block sit in Tonowanda for 6 months?

This looks like someone not having dates straight in their mind and thinking casting months were the same as model year months. That is, they thought A-Aug, B-Sep, C-Oct, ... G-Feb, H-Mar, J-Apr, with no I.

Even then, J 18 8 would not jive with 0402 but some people really get mixed up.
