Hello,

Was wondering if someone could post any block date codes that they know of for a 70 Firebird/Trans Am Ram Air III out of Norwood with an April or May build date. Just trying to get a sense for the range of blocks that could potentially be used on a car that has a fourth week of April build date. Seeing quite a wide range of block date codes. Anything from October of 69 for a car with a later date on the invoice than mine, as well as a later production sequence # (by about 2000) to March 1970 from a car that was ahead of mine by 6k units. I guess either one would be fine according to the sequence and build dates, especially given situations where blocks could be sitting somewhere in inventory or misplaced, curious to see what folks out there have in their TAs.

Thanks.

My original block is dated 12/69 on a July built car.

My 3rd week of March 70 has its original engine, which was built in January of 70.

My '70 Formula is a 04D Norwood build car. Here are the date codes on it:

Block - D060
Heads - D100/D140
Int. Man. - C100
Exhaust Man. - D080/D080
Carb - 0570
Dist - 9G3
Alt - 0B23

I hope this helps! It looks like dates are all over the place!

I had a weird combination of dates on a low mileage 70 T/A automatic I parted out. This was a low mileage but rusty one owner 70 T/A I bought out of WV. I don't remember the exact dates, but the interesting part of this is the block had no VIN number stamped into it. I believe the body shell cowl tag was dated a couple of months before the motor, with the motor cast dates matching up what you would expect for a July shipped car.

This is the second engine I came across with no VIN stamp or SR block stamp at all. The first was a 1971 455HO YE block. If my memory is correct, someone on the board said that if there is a problem with the engine, the car gets pulled off to the side and a replacement engine gets installed. When that happens, the people replacing the motor usually didn't stamp the VIN into the block because the rework was done off the main assembly line.

The original WS block in my 04D Norwood Formula is dated D 10 0.

Wow that's a big gap. They probable had a special high horse motor in the back waiting for your car.

They were using it to hold the bathroom door open for 6 months

I’m always interested in hearing what some of the experts have to say on this huge gap between build date 7c and block date 12/11/69.

I have found that sometimes an engine in production line did not pass inspection and was passed on to the "backroom" for repairs and when finished back on the line. E.U.N and V.I.N was stamped at installation in the vehicle.

Thanks!

70 Birds seem to be all over the place with VINs, EUNs, Body #'s and others.
I think some of it might be the beginning of 2nd Gen Birds was in the middle of the model year?

[johnta1]

jhnichols2 list of dates is good. Probably should try that with my EUN page.
(but it's hard enough to just get the block dates or codes)

Do you have the axle and tranny dates/codes for the TA?

Maybe the Engine Plant used a First In Last Out inventory system....?

The closest other RAIII EUN I have to yours (~140 before) in my notes is in an 03D Van Nuys TA.
