1974 Chev Corvette Stingray
 

Hello together

I am starting the restoration of the C3 1974 Stingray...

The poor thing has been in a barn in Switzerland since 2002.....

Now unfortunately I don't have a matching number, but that's not as much in demand here as in the USA. The engine is a 5.7 350CUI... but some of the numbers are unclear to me, Especially the number 66000 (which was obviously stamped in later) doesn't make sense to me!.... See the picture in the attachment....https://cimg5.ibsrv.net/gimg/chevrol...daa4660ec.jpeg
66000 (???)
10C169605 (1-Chevrolet, 0-1970, C-Southgate, California, )
T0414CNR (T-Tonawanda, 0414- April,14, CNR-1970 350 tur hydro trans - 300hp used in Impala/Caprice/Bel Air/Kingswd)
3970014 340261 (???)
GM5

I did find out that it could be from a 1970 Impala, but I'd appreciate any information I can get so I can install the correct parts. Which tuning parts were available back then (I can install these (Restomod is almost impossible here...))

I am looking forward to your answers and information :)

Thank you very much

While most small block mods with fit most small blocks, it would be best to check with the supplier about your specific block. Also should check to see if the block or heads have been machined at all because that will affect the intake manifold fitting.

Thank you very much!
The engine is in factory condition but not the one with the matching number.
So I want to know what was installed or can be installed.
Many thanks and greetings from Switzerland
