I am in the process of a time-correct engine swap
(a 1991 5.7 L Corvette TPI engine (L98) for my 1991 RRC).

To skip the process of an individual emission test (which is not easy to organize and not cheap at all) the registration-authority would also accept „official“ values from already existing car-papers of an Overfinch 570.

If you have some or know somebody who might have one that would be great.
Of course I contacted Overfinch aswell but do not expect support from there.


Best regards
Gunnar

I got the obviously rare information by chance from an enthusiast.
Very happy. Thanks a lot.
