Default Advice Needed

I've got a '75, interior, frame and body are in good to excellent condition. But its an L48 with an automatic. I'd like to put a 300-350HP crate engine in it and drop in a Keisler 5 speed. With the other little things it needs suspension wise, I'd be looking at around $15K (Canadian $, so $13K US).

The question is, if I had to sell the car at some point in the future, would the car be still "just a '75"? As in only worth what a typical '75 is worth? Or is the money I'm putting into it going to be worthwhile?

Don't worry too much about the future value of the car. If you like it, enjoy the ride. If you want a collector's car buy a chrome bumper with matching numbers or better yet a mid year.

I would suggest keeping your old engine. You never know, C3's may take off in value someday and originality of these cars could become important.

I'm not so worried about the "value", as spending $15K on the car... something happening in the life that required selling the car and still only being able to sell the car for $9K because its a '75.

That is a valid point. If that were to happen, you will have limited the marketability to those looking for such a car. When money is put into mods on these cars, rarely, IMO, can one recover such costs. There are many Vette enthusists that have no interest in buying such cars. But on the other hand, if you would enjoy such a mod, that is worth something in itself.

The general rule is that any money spent modifying a car is thrown away when you sell the car. Generally speaking, you will most likely only be able to sell the car for less than what it's worth in equal condition with the original drivetrain.

The exception is when the work is done by someone noteworthy, like Lingenfelter, Callaway, Coddington or the likes. Even then, it just depends on if someone who sees the car happens to like it.

Most folks that think their car is worth much more because they put $15 or 20,000 into it see their car sit unsold until they lower the price below what a stock one goes for.

If you go into it with the idea that any money spent now is for your enjoyment and won't be recouped when you sell, you'll be much happier in this hobby.

If it was me and I was going to do it, I'd keep the original(if it is...if not, it doesn't matter) motor/tranny and store it properly to be swapped back in when you sell the car.

I agree with okinawa86vette. These cars hold their value in their original state and they are what they are worth. If you have a 76 it will always be a 76 and be worth what it is worth.

Mods don't return dollars because they make a car what you want it to be. Unless you find someone who is looking for that exact combo it is difficult to sell for more than book value.

You are going to put in a 300 HP crate engine and a 5 speed for $15K. I would put in a 502 big block an a 6 speed for not much more. Someone else might want a used 427 big block with a Muncie for less money.

You will never get your money out of a small block conversion or a big block conversion. You will get more for a big block but never close to what you spend. Look for a car that someone else has done these mods to and see what you can buy it for it will be much cheaper.

Related question.....
Would "building" the ORIGINAL engine to achieve better performance reduce the "value" of the car??

OK, I'm new at this Vette V8 stuff, and dont want (ok cant afford) a 500hp car, but I'd like to ultimately improve the performance of my '72 350/200/Auto.

Please dont tell me "well you shoulda......"!! I have what I have, I lean towards originality, I KNOW the true value in these cars lies with originality. So, my question is simply "would modifications to the original engine (intake, exhaust, compression) reduce the value of having an "original, numbers matching car" ???? I'm just looking for a little more seat o' the pants power, but driveability and dependability is very important. I'm sure theres a lot of us out here who dont want, or need, or simply cant afford 500hp!!! Sure I dont have a BB/4 speed/Vert.... but a rising tide floats all boats, and dont want to ruin the future value of my little Vette!!!


Thanks Guys!!!

What folks can't see can't de-value a car. What I'm getting at is that if you swap to aluminum heads, an aluminum intake, super big cam and stroke it, folks are going to know right off the car's not original.

But, you can sneak in a little extra cam with no one the wiser. If you swap intake or heads, just keep the originals to either pass on with the car or swap back on before you sell.

Those "stock" drags are all about what you can do with the car being original....or at least sneaking by the techs as original. It's easy to pull the valve covers and see roller rockers, different heads, etc, but it's a lot more difficult for someone to verify the cam's not original.

Like I said, keeping the original parts does a lot for the value.
