Default Matching number motor vs driver/beat on motor

What are the all wise thoughts on putting a 74 motor to run and put miles on while the rebuilt numbers match motor waits till I ever want to sell the 71 vert. It will be fresh if I sell the car. I can get the 74 w/69000 miles that runs well for a great price.
Thoughts?

Doesn't make sense to go through all that to me and still have to explain why the motor has less miles on it than the chassis. Put the rebuilt one back in and enjoy it.

I would hate to rag on a numbers matching motor and do possible damage and lessen the value.

Sounds like you answered your own question.

you would be doing 2 engine swaps and then in order to get a better dollar, you would have to convince a buyer years from now that the engine has less miles on it than the chassis.. something I would find fishy if I was that buyer.
I don't know what that better dollar might be? a couple hundred?

anyway, a well broken in ( but not worn out) engine is more value to me than a freshly rebuilt one built by who knows who that a good subset start leaking or knocking within 1000 miles.

then you would have to sell your 74 engine too... another pain in the butt, shipping, negotiating, etc...

I was under the impression the number matching motor in the car is a 10k difference. Im not sure.

the difference in a freshly rebuilt original motor vs a well broken in original motor at selling time. i think that is what you are asking..

a numbers matching car, vs NOM with all the same criteria is about 25%.. more for highly desireable big blocks, and less for base engine cars... ballpark..

My matching block is under the bench while I experiment on my current 327 and see if it likes going to the 6800 MSD set red line. I have no fear of having too much fun. Eventually I'll get the original machined and put back in when I'm sure the combo wont explode. If you have a good setup for pulling the motor it isnt a big deal.

In my opinion....., repeat "my opinion only"......, build the car the way "YOU" want it. Daily driver, weekend warrior, wash and show, garage queen, trailer queen etc... Don't worry about resale until it's time to sell, which shouldn't be until after your dead. If you have money to invest then you should invest in the stock market. If you want a fun toy, then buy/build a Corvette and enjoy it for what it is, a cool sports car with a ton of history... Good Luck with whatever you decide....

Spot on there. A corvette is a lousy investment but you can’t drive and enjoy your 401K either. Drive the wee out of it anyway you want and worry about selling it and it’s value later on. Me personally I could give a crap about numbers matching. I’d rather own a fun car than a dull base motor low Hp version that any Honda out there can beat. JMO!
