As far as thinking this car would have any value to restore you would be making a big mistake. To restore this thing hoping to get your money out of it would be a waste of time. Even if it had the original motor you would most likely be on the losing end. Finding a correct big block will be at least $7-10k built. Paint will be $10-15k. Finding the right interior one off parts for a 68 will drive you nuts and cost you money. Big block hood $1k. Everything else maybe another $10k maybe more depending on what it needs.

If you want to have a car to have fun in and drive around then go for it. But I wouldn't drop too much money into this.
I do all my own work, no labor just time. Mechanical, electrical, interior work, and paint. One stop shop in my backyard, just gonna take me 2-3 years and I'd speculate 10-15k in parts plus my initial investment and while it may not be Bloomington gold correct it will be a darn nice car you can drive anywhere.

What about parts and materials. I do my own work too and this will eat up the dollars. Correct parts are a forture.

You still have to find a correct engine, then a correct carb another 500-1000. Same for an alternator, starter, etc.

That's why it's not really worth going the "collectible" route as the collectors want to see these things but they will not really care if the drive train isn't original anyway.

Even if you do your own paint work then you know what it takes to paint a car.

If you like doing this sort of thing (I enjoy it) then have a blast. But you will not be making any money. Not even close. It's not worth your time on a car like this.

If you have the time and talent, find one that is more correct.

I hate seeing guys get burned on what they think is a good deal.

Good luck

Not looking to make money, it's a hobby, it's for fun.
I'm not looking to make this a nut and bolt original trailer queen. I just want a darn nice car, if I can get lucky and source a correct engine down the road great, but I have a 502 just taking up space that will fill that part for now.

I just want to know what I'm buying, I like to know everything I can that's why I'm here. What is a mismatched but solid 68 vert worth? Is 12500 too much to pay for a good set of bones? I may resto mod the car like my 67 mustang, those purists on that forum went for my throat at every post, but I sold it for double what I had in it. But i never expected that, it just happened...I enjoyed the build and the conversation from other enthusiasts

Here's what you can do that will pretty much answer all your questions.

It sounds like you probably have a nice shop with good tools at your disposal. Do you happen to have one of those cameras on a wire? The kind you can stick down a radiator for example to have a look around on the screen.

If so, take it and look for the tank sticker, which is the build sheet for the car. It will be located (hopefully still there and in one readable piece) on top the drivers side of the gas tank. You can see it by just pressing down on the rubber filler neck boot. But the camera will help you read it.

You never know, it could be a aluminum head L89. If it is, don't start jumping up and down. Just take the car and go......

I do have one,was going to take it and scope out the frame rails but that is a darn good idea to look for the tank sticker with it! Thanks, I won't hold my breath on an L89 though....but as my buddy tells me, "They're out there..."

Great tip!

Correct. Not to overstate the obvious, but the console trim plate has been swapped.

Based on what has been posted, there's more going on with this car than just an engine swap.

Even if you do find the build sheet on the gas tank. you may not be able to read it. But it is worth a try. Mine was half gone and covered in dirt.
Just thought Id warn you.

Yes, I don't expect to be able to read it, but if all the other items look right and I can at least see that the sheet is there, that may bring a little more comfort.

Just to add, the seller is not trying to pass this off as anything. He told me he does not know if it's a real big block car or not, only that he knows that the engine is a 350 and he believes it was a big block car. This is one of those "It was my brothers car, then my dad bought it, then I bought it" deals and none of them apparently ever did anything with the car.

Currently I am not planning on trading, but ask me again in a couple of hours...I do plan on looking at it, have warned him that I intend on removing panels, and looking at it closer than anyone has looked at it in a long time. Made my intentions clear and that the most I can promise him is that we may have a clearer understanding of the history of the car and a good conversation, however if I like what I see then perhaps we will do business. To which he agreed.

Thank you all for the tips, I have a nice list here to go by. Really the only thing I can think of is lets say the off chance I can read the build sheet and I see 427/435....then I may come home with it.

Thanks, I mean after all it is a running/driving all there 68 convertible, they are getting harder and harder to find, so its worth something. I will have fun looking at the car regardless of the outcome.

Thank you

Default I had the same question on my 68 454

I had the same question on my 68 454 NOM and did a post back at Christmas, here it is, plus the feedback I got at the time, all comments are welcome:

I was curious as to how you could actually tell if a C3 was previously a "big block" car.

1. has the 5600 red line tach
2. has the 427 hood
3. has rear stabilizer rod or sway bar 9/16"
4. has 15/16" front stabilizer rod
5. larger indent in cross support under the engine for BB harmonic balancer (Maybe? thought I read this somewhere for C2's, but maybe dreaming, ha!)
6. rear end U joint are caps not straps.
7. no holes on the passenger inner fender for an expansion tank, indents in the fiberglass, but no holes since no expansion tank.
8. 23x17 copper radiator core with no expansion tank.
9. front springs little green code sticker for BB's, HU or HV
10. correct coded rear



Hope this might help, I agree, while I thought it might be cool to say my 68 was a BB car, in the end, I think you have to price it with the NOM engine in the Corvette now, BB a little more, SB a little less.

Good luck in the hunt!

I would love to see some inspection photos and get your take on this car even if you don't buy it.

10-4, I wish my scope took pics, but maybe I can take a pic of my scope with my phone if I see anything interesting (like L-89 code on that build sheet- Hah)

Anyone have a pic of their inner fender where the expansion tank would have been? He sent me a pic with no expansion tank and I see 4 dimples in a rectangle maybe 4 inches x 3 inches, hard to tell with no reference. Is that the right place?

Also car has 7 leaf spring

That is it. I had the same dimples in the same place on my 68 454 NOM. In my case, since I wanted to install Vintage Air, I bought a 69+ DeWitts big block radiator which required an expansion tank so I had to drill out the dimples to mount the expansion tank. Kinda of hated to drill the dimples, but hey the 69+BB radiator is bigger than the one I could have fitted if I stayed all 68. More radiator is good in Louisiana.

Good luck with the purchase. I am thinking unless you see body work around the hood surround and fenders and so the inner fender might have been replaced (but who really knows), the odds go up that this one could have been a big block. IMHO, check completed ebay and Mechum for pricing on 68's with NOM SB's. Again, just my 2 cents, I personally would not pay any premium for "used to be a BB car", you are buying what it is right now and want to pay a fair market price (or less as a buyer,) Again good luck with the hunt, Jan/Feb is a buyer's market for great deals.
