Q. What is my Valiant/Barracuda worth?

A. In theory: Values vary widely upon condition of the car, location, and model/year. It is very difficult to put a price on a vehicle without inspecting it. For a ballpark idea, look through some classified ads on our Links page. Join our mailing list. See what similar vehicles sell for on eBay auctions. Go to the Hemmings Motor News website to view ads, or for a price guide. Or see the classic car section of NADA online. (Be aware that the average marketplace pricing may or may not match any of those ballpark guides. The final price will depend on whether you're anxious to buy or anxious to sell.)

A2. In practice: Although these can be nice cars, they are generally not considered to be expensive investments. There isn't much difference in price between 1964, 65, 66 models, but there can be a huge difference based on condition. Barracudas typically fetch between $0 and $10k USD, Valiants about half of that, and converts or other "special" considerations are somewhere in the middle. Needless to say, it takes a pretty spectacular car to push toward (or even beyond) the upper edge of the envelope, though it's not unheard of.

A3. An object is worth exactly what someone is willing to pay. No more, no less.

Q. My car has a slant 6, but i have a 340/440 in the garage, will it fit?

A. These cars are considered "A" bodies, but narrow "A" bodies. All of the 273,318,340,360 Small Blocks (all physically the same outside dimensions) will bolt in with almost no modification, since a V8 was a factory option beginning in 1964. But even with a small block, it's a tight fit, requires special exhaust manifolds to clear the steering column, and generally leaves not much room for your hands to get in there to work on things. This early body style was clearly designed for the 6-cylinder powerplant, and the engine compartment didn't get wider until the 1967 model year.

On the other hand, the 383,400,413,440 are Big Blocks, and the engine compartment was never designed for these engines. Not even close. They will fit with lots of modifications. A welding torch, a shoehorn, and a little vaseline would be helpful.

(But people have done it. Just so you know, a big-block narrow A-body is generally considered a nose-heavy pig that isn't anywhere near as fun to drive and probably will not be even as fast as a healthy small block car. Not only will your working access be even more limited than it already was, the engine won't produce anywhere near the power it's capable of because there is no room for an exhaust system of sufficient size, unless you cut up the fenderwells to fit the pipes around the front wheels. If you're saving a rust-bucket from the crusher, and you like playing with your welding torch, this approach might be justified. Please don't destroy a good specimen like this. We have many members who would gladly trade you their rust-bucket, I'm sure. -ed.)
