JohnZ, What about a '68-'69 SBC with a single digit for the year, possibly no front plug, but stamped with a Tonawanda assembly-date/engine-i.d. stamp? Until I confirm the front plug, is there a possibility Flint blocks were shipped to and assembled in Tonawanda?

Definitely. The year portion of the casting date code on a Tonawanda block is two digits, and it's only one digit on a Saginaw casting (like C 3 9 on a Saginaw block, which would be C 3 69 on a Tonawanda block. Also, Saginaw/Flint blocks had a 1/8" NPT square-head plug in the front of the block, just above about 11 o'clock on the timing cover; Tonawanda blocks didn't have the hole or the plug...
Does that apply to Small Blocks, specifically trying to identify any differences between a Tonawanda cast small block and a Flint Casting.

Foundries never shut down - the melt cupolas ran continuously, although pouring of castings was normally a six-day operation on two 10-hour shifts; the Saginaw and Tonawanda foundries each produced about 55,000 castings per day for their respective engine plants. The Flint and Tonawanda engine plants ran the machining departments on three shifts, and assembly on two shifts, producing about 5500 engines per day each (one every 12 seconds).

Castings "typically" were machined within 2-10 days, although it could be much longer depending on inventory and demand for specific castings; production scheduling and inventory control in the 60's was nowhere near as precise as it is today.

Is there a way to identify which foundry a block was cast, ie: Tonawanda vs Flint?

just don't go any earlier than a month and not later than about 5 days prior to the engine assembly date. : )

Actually, it can be closer than five days between casting and machining/assembly; his block was cast on September 8th, and assembled the same day. Although it's not the "norm", we've documented a number of Corvette small-blocks from Flint that were cast and machined/assembled on the same day (cast early on the first shift at Saginaw, assembled late on the second shift at Flint). More "normative" separation, however, invites less scrutiny.

Are you saying you have documented heads cast the same day as the engine assembly?.

I would say H 30 9's give or take a few days, typically 10-14 days before the engine assembly date is ideal, nothing set in stone on that one, just don't go any earlier than a month and not later than about 5 days prior to the engine assembly date. : )

Not necessarily, just that he is my neighbor 2 doors away from me, I had seen this car a very limited number of times over the last 2 years, he kept it stored away from home and didn't take it out too often. I know Ralph was under the impression someone had done a poor job of trying to restamp the vin on the block so it's good to hear it may well be the original block. I do know the intake on that car is for a 67-68 Z28 and not a 69 since it had a aftermarket dual quad setup on it when he acquired it. Otherwise a very nice car, glad to hear it stayed local.

Decoding/Numbers / 69 L6 Camaro base price

Anyone know what the base price for a 69 six cyl Camaro was for a Jan '69 build?

Detfox, did you recently purchase that car from a gentleman named Ralph in San Dimas?  Stamp looks familiar, 4B build date seems familiar.

So did the window stickers for '69 also reflect the change from Los Angeles to Van Nuys if at all? I've seen both, whether real or not?

Hey Zackan, did you fix or find the problem with your tach?
just wondering.

I experienced the exact problem, sounds like you need a tach filter, are you running electronic ignition? Try this easy and inexpensive fix, worked great for me and I installed it in the harness near the drivers kick panel out of sight.
