The Best of Corvette for Corvette Enthusiasts
Its been WAY TOO MUCH FUN modding the heck out of my plain-Jane, 72, SBC, auto, T-top, low-optioned coupe!!
I certainly can appreciate why some of us wish to go the all original route.
Otherwise I see very little difference between a car with 'correct' major components, proper casting numbers and date codes, and one which we assume to be the original. NCRS sees it this way as well. A car with correct components but without the 'matching number' suffers only a minor point deduction. The point being the car is presented as they were typically built in the day.
If I were inclined to swap out the motor for another as we commonly did many years ago. No, numbers wouldn't mean anything, quite the opposite. I wouldn't pay the premium for a motor I was going to pull out.
Yes, to some, numbers are the most important attribute of the entire car. A pedigree. Most often when we're talking about a high performance version or a rare copy. For others who may have bought numbers in a high market prior to 2008, of course they're important...

A fool to not consider their effect on market value? Maybe, but I don't think I've EVER heard people who declare others to be fools come forth with any measure of how much it affects value. Never with any proof other than maybe a handful which passed through auctions. Are buyers fools or are numbers being pushed to suit someone's financial agenda or personal bias? Apparantly some care a great deal, others not at all.
that is awesome my dream for my 79 is a ls3 or an ls6 with a t56 that is just bad *** Rogman





While I may well agree there are obvious examples which ought best be left original, just because resale value may not be every enthusiast's primary consideration doesn't necessarily make them all foolish. To say so is, IMHO, somewhat of a personal and rather inappropriate attack.As for the OP's actual question, for my money it depends very much on the example in question. For instance, there having been over 15,000 1978 SAE's produced, they ain't exactly rare, so I have no regrets for having made what I consider a number of improvements over the years, but I doubt I'd hack up a genuine matching numbers one today. That said, if given a choice between the two, I'd choose my ragamuffin over any museum worthy SAE every time. Tho obviously an intolerable thought for some, there's something quite liberating about not always being restrained by originality.
Seems to me that the '77's I see are not worth much $$ wise and even an extreme example where it is ultra low mileage and original everything doesn't sell for much. Just not worth it to worry about numbers on the mid to late 70's models IMO.
Have fun and build it how you want!

The previous owner to the PO I bought the car from had the engine and trans re-built so I still have the factory block and intake. He also added headers and I had to get a new water pump, so I am leaning more to modding mine and not worrying so much about keeping it all original.
Being a 75, I think it will be more appealing to potential buyers if there are some upgraded features.
Just my thoughts on the topic.
On a 1969-1970 big block I'd be obsessive about "correct" but I can't afford one of those beauties. Maybe, that's a good thing (at least I'm trying to tell myself that), because I'd probably be afraid to drive one. If you damage a "perfect" survivor or significant Vette the heavens will open and swallow you whole.
I like a car I can make tasteful, subtle modifications to and enjoy driving around. ( I was going to put in an obnoxious, heavily modified corvette limo wagon mudder picture here but it's Friday and I'm feeling lazy) Someone else is free to do so, if they feel up to hijacking this thread.





If I had a 1980, I would likely pull the motor, slide in a small block 427, a 5 speed, paint it black and drive the crap out of it - with little concern for value - because I would be loving how she runs.
If I had a 1969 427 Tri-power car - there is no way that I would cut this up. I would restore it to NCRS spec's and love it - and watch the value grow - as it was a work of art when it left the factory.
