Price difference 67-390 vs 435HP cars

[Ron R.]

I'm looking at comparable quality 67 roadsters. Both are green big blocks. One 390 hp, the other is a 435 hp car. Both have great documentation and appear to be real cars with original engines, carbs, etc. In today's market, what should be the difference in price between these 2 cars? They are between 2-3 on a 1-5 quality scale with 1 being Top flight and 5 being a project.
Thanks,
Ron

Ron,
This is too vague to know anything or to comment in any detail. Great documentation means one thing to some, and nothing to others. Do you have the name of every owner title transfer date and how many owners for each car?

Do you or the sellers have the NCRS shipping report and have you compared that data to the other documents? Namely tank stickers??? that may have been "reproduced or worse, faked to show the additional 100 cubic inches and or 435 HP option.

Sure someone is going to tell you the 435 is worth more, but it won't be if its fake and someone finds out.

The there are the cars themselves and the fine details of their conditions, restoration or not so on your scale statistically speaking, price should not be materially different.

I know of two recent sales of 66 390 HP Coupes. Both Nassau Blue & white. Neither one had original drivetrain components. Both had 427s from passenger cars, 1969 & 1970. Both very clean repainted southern cars, one never hit. One sold under 40K, the other fetched 45K.

Ron,

Here's probably the best answer I can give you. From the Keith Martin's Corvette Market 2011 edition. 427/390 L36 convertible $62K low $109K high. 427/435 L71 convertible $95K low $187K high.

A friend of mine recently bought a '67 427/435 convertible for $84K and it received a Third Flight ribbon in an NCRS event.

I don't know the answer to your question. But why is it every time The show field has more 435 hp than anything else. It just amazes me how so many high performance cars survived with matching #'s engine.

I have heard comments that most of the 435 horse cars are fake in some way or another. Made up all together as well as stamped motor jobs. Now the big thing is fake paper work.

I would advise you to go for a 390 horse any way (assuming you just had to have a BB) since this is a much better street choice.

My choice would ALWAYS be a SB, much more "comfortable" to drive. It also eliminates the possibility of embarrassment of getting blown away by a strong small block, even worse a late model Mustang or Camaro.

My $0.02 is this sounds reasonable.... The high end buyers want a 435 hp car. It would have to be a very high option 390 hp in mint condition to approach the price of a decent 435 with a good pad and paperwork.

My thought is, buy the best car with the most paper work and owner history that you can afford. There is a big difference between
"matching numbers" and "original engine". Looking at the Judge Sheets from a recent NCRS Regional or National will tell you a lot.
I also suggest that when you go to look at a car take a knowledgeable person that has no personal involvement with the car.

Gene has a point, a late model Mustang sporting 500 HP will dust off one of these C2's regardless of what's under the hood.

I don't think anyone who is buying a 435 Corvette today is looking to street race it. I am sure that a 2050 econo box will destroy a 2011 Mustang in a race. I hope that I am around to see it.

Steve, probably true, there won't be petrol around for the Stang or the Vette, transportation for the rich will be the plug in EV, and the rest will have a bicycle.

I agree with the above. However, if the 390 hp BB has factory A/C, that could be a big consideration if you want to enjoy driving your car in the summer. And, the A/C option would add value to the 390 hp car.

My last concern is that neither could have been a "factory" big block car since there is a huge financial incentive to cheat. For example, when was the last time you saw a '69 Camaro with the six cylinder engine it came with? They are nearly all SS396s now. -Clark

I'll give you a "shoot from the hip" number. Since we're talking green, (I've had my share of green Corvettes) my number would be $20,000. If it were a red '67 Corvette, the number would be greater. This takes into consideration that the 390 does not have a rare option like AC or factory mounted side pipes. Now I'll wait for the comments.

I think that's a good number in general, all else being equal.
