Cowl Tag: Removed or not?

Looking at a car with this cowl tag. Noticed that the rivets looked removed, not sure if its actually original to the car. Is there anyway to tell for sure?

Does it still have the original blue door sticker with the VIN and date code matching code on tag? 930= black bucket seats. No guarantee, but it's a good start.

Unfortunately, I'm not around the car so I can't verify some of that. From other pics, it does have the black buckets and is red like the cowl tag. Could 05C and been a production date for a W30?

I think I recall seeing June on a cowl tag or two. But you may want to go to C.O. and post this question over there and I believe you are a member too?

The rivets are not there

LOL

same car has what looks like a 74 - OA code transmission? I'm not sure anything about it (any information guys?)but its starting to definitely seem pieced together some. Unfortunately, I'm not really close to it to personally check out.

That comes up as TH350

Can that even fit with a 455? Removed cowl tag, strange transmission combo.... seems fishy.

i guess I would go with Joe P's info on C.O. The chart I gleaned it from was from the internet, now I trying to recall the website I got the information from.

I got a lot of information from 442.com. This was an interesting piece of it comparing the two:

Consider this- why did the factory put TH-400s behind the big-inch engines, while the TH-350 was put behind the small-inch engines? Because the TH-400 can handle the increased torque. The TH-350 has a lighter internal rotating mass, but must be modified to handle increased torque loads. With this done, it will make a good performance trans. I particularly like the TH-400because you can beat it to death and it is ready for more. The only transmission I've ever killed was a TH-350. I put it behind a modified455 and thought I might get away with it. It was fine until I put a good hooking set of slicks on the car. I've yet to destroy a TH-400.

If you have a 2000 stall torque convertor for a TH-350, you"automatic"-ally have one forthe TH-400. They will interchange with each other. But, depending on the torque input, that stall speed is raised or lowered from that "general"2000 stall reference point. If you are going with a modified engine,and a lot of horsepower and torque, you will have to modify the TH-350to equal the load capacity of a stock TH-400.

Well, then, I'll say it now: the TH-400 is a better tranny. But, better for me means more reliable for everyday use on the street. Better forsomebody else might mean it's 3/10ths of a second quicker through the quarter-mile when sufficiently modified, in which case they'd consider theTH-350 better.

As Joe mentioned, it may actually be a TH-375 which I have no idea on quality/reliability for.

TH-375

A medium duty version of the TH-400. On the underside of the trans, right where the tail housing bolts up, the letters "TH-375"can usually be found cast into the trans housing.
