Nothing personal Tim as I love 'Vettes and understand how this whole Chevy numbers things has really evolved from the 'Vette collectors and judging groups, BUT...personally I still have a problem with ANY restamp. .
Couple questions...Is a 'restoration motor' ever an original born with motor or always a correct castings/dates motor with a 'perfect' rebroach and restamp? .
And are 'restoration trim tags' Ok in the 'Vette world yet...seriously?

.
Again, personally I'd prefer a replacement motor be as correct as possible with castings, dates, suffix correct too if possible, BUT...left alone as far as broaching/stamping goes! .
