How much effect do matching numbers have to do with the value of the vehicle? Vehicle in question is a 1967 Fastback, excellent condition. Was originally a 6-cylinder, now has late model 302.
Thanks.

 

On the rare cars it could mean my guess around 30 to 50%. On the mass produced cars much less as often these are ramped up with bigger engines and often enter the world of "Restomods". On the flip, I think that maybe someday the matching number originals values by far will excede whats beingrestoedtoday. Each day it becomes harder to find cars that are all there. Just my opinion.

 

Unless your mustang is a low mileage survivor car, it is going to be worth much, much, more with a V8 than the 6.

 

UH OH ..... here we go with this debate again .................

 

By what I've seen, they usually hold better value.

 

Even 6 bangers?! Who would be collecting those?

 

no typically ok maybe 98 percent of the time a V8 swap is a value increase.I agree with evil.I think any time in the somewhat near future unless an ultra rare car, the bigger and better the upgrades the more valuable, however that said the more of us that do it, that means there are less of the untouched cars so once us "restomodders" get our hands on enough of them the untouched guys will have very valuable cars.SO that should end the debate, we are doing you guys a favor Your welcome

 

I disagree. The only reason to have a matching number car is for collectability.There are still plenty ofwell optioned '67 V8 Fastbacks left that I don't see any reason for collectors to start chasing 6 cylinder models, most of which were strippers.

 

I 4 one like my 6 popper because all the oldies will disappear from the junk yards and such ,,,thus if you can't find/get one the value goes up....muscle cars are in the own area and own value,,,, choice will be simple in a couple more years pay thru the nosw for a kit or pay thru the nose for a " real " car,,,just my opion

 

Depends on if its a concourse car or just a normal restored car concourse is a 100k car most times but they are the way they rolled out of the factory all the tags on the engine the lines painted on the driveshaft and sway bar.I did look at the prices for a 67/68 fastback here around 8k cheapest no matter what engine it has but a big block car is 12k up.You can look at the price of the gt500e which is a restomod they aint cheap its up to you but dont do anything you cant put back easy just incase you change your mind.
