1970 Build date

[Jordan S.]

My 1970 convertible trim tag shows date G07. Is this July 07, 1970 or February 07, 1970? My protecto plate shows a build month "7" and my engine number is T0702CZU (July 02, 1970?)

Do these numbers "match"?

Re: 1970 Build date

1970 was an unusual model year. Production started in January, 1970; so G07 = July 7, 1970. Of course that is the seventh month of production, and your Mark IV engine was assembled at Tonawanda (suburban Buffalo), NY, on July 2.
I intensely dislike the term "matching numbers" because there is no generally accepted definition of the term. Let's just say all those dates are what one would expect.

Re: 1970 Build date

Terry....I agree whole heartedly...matching numbers has become a very loosly used term. I have seen a lot of matching number cars that in reality the only numbers that matched were the front and rear license plates!! Today the new terms that dealers and auction houses are over abusing are 'tribute car" and "date code correct" to sway the unknowing buyer in to thinking they are buying a real car. It's sad but true.

Re: 1970 Build date

Jordan congratulations on purchasing a one owner 1970 Corvette. I still have my bought new 1970 coupe. Your cars numbers are close to mine. I have a G08 on the trim plate and the "7" on the protecto-plate. My engine is a SB but has the same date as yours, V0702CTG. What are the numbers for your rear end? Mine are CAV0702W. My trans is a turbo 400 with 70CK4275 stamping. Having the protecto-plate is great to verify the numbers on the engine, transmission, and rear end. I lost my original alternator when it was replaced under warranty.

Hi Jordan,

I also have a 70 LS-5 with the same engine stamp as yours T0702CZU. Like yours, mine has a manual 4 spd with PS. It looks like mechanically, ours are very similar. I'd like to compare notes sometime.

Re: 1970 Build date

Jim, I have not been under the car to check the rear end or transmission yet but the prior owner stated they're original. Protecto plate number for rear end=CAT0505W and trans=P0H15. The car had not been registered since 1999 when I aquired it and is in need of some TLC.

I'm doing the front suspension/ brakes and cooling system this winter. Trying to resist the "while I'm at it syndrome" so I'll be able to enjoy the car next spring. I too am missing the original alternator, in addition to the water pump.

Re: 1970 Build date

Jordan according to the NCRS Specifications Guide your CAT rear end is an 3:08 heavy duty. You can probably shift at WOT at least at 60 mph from first to second and about 90 or more from second to third. My SB is an 3:08.
