Decoding/Numbers / block build date
« on: January 25, 2010, 09:34:28 PM »
OK, the blocks build date is usually about 2 weeks ahead of cowl tag date, what would the dates of the carburator, distributor, alternator etc be? Would they be closer to the block build date or the cowl date ?

A straight line 'I' ok, but I"ve seen a Roman numeral 1(a straight line with a cross bar at the top and bottom) and didn't know if it had a specific meaning.

However the 3914678 block was used for 302, 327 & 350 assemblies. Just different goodies inside.

Thanks again...I assume 291's that came with 2.02's had the unshrouding done at the factory?

OK thanks, BTW what woukld you think of an original 3914678 302 68 block with a casting date of D-1-8 and assembly date of V0526MO? Sounds a little fishy to me since most block assemblies were done usually within 10 days of casting date.

The starting body assembly date on my 68 Z/28 cowl tag is 04A(April 1st week) and my VIN # is 123478N4 _ _ _ _ 5( I deleted 4 numbers for security) and according to the numbers posted on this web site, the VIN # calculates to the fact that the car was completed the 8th day of April 68. The calculations were made using the last VIN # produced for March 68 and the last VIN # produced for April 68. For the month of April 68 18,227 units were built, and using a 5 day work week there were 22 work days in April 68, this means around 830 +/- units were built per day((3 shifts). Now if the VIN # were sequencial by 1, I multiplied the 830 units per day X 8 = 6640, I added that to the VIN # of the last unit built in March 68 and my VIN # falls into that range. I do not have the origional motor to check the assembly date stamped on it which would have helped in determining the final production date. My reason for doing this is because I am restoring my Z to origional matching numbers and the only thing that is not original is the motor, as mentioned before, and in my search for the parts I have to find them with the right casting dates. The correct casting dates would be within 10 days of the final assembly date. IF YOU FIND THIS IN ERROR PLEASE REPLY, THANKS.

Is there any reasoning that a (1) is sometimes coded as a roman numeral (capital i)?

The 3917291 heads come in two types, one comes with 2.02/1.60 valves and the other comes with 1.94/1.50 valves., both are 64cc.Does anyone know if the castings are the same and they are just ground for the different size valves?

My concern was the crank (#3911001) weather it was a lg or sml journal. A lot of web sites have conflicting reports. EBay # 2705185634825

Did Chevrolet make a 327 in 1968 with a large journal crank? Casting # 3914678. I found a 327 on E-bay with that casting number but stamped vin says it was from "J" plant.

If I can't find an origional Z/28 distributor # 1111467 what would be my next choice? A 67 Z/28 distributor #1111266 or a 69 Z/28 # 1111480, keeping in mind that I'm trying to stick as close to origional as I can. Or does anyone have a lead on a 1111467?
