1967 Corvette

Hello for todays market thats not too far off, now if it was a L88 -9 thats a different story with the tri power aluminium heads. Reading that you said it was 400 hp that would be a single 4bbl carb. Thanks Norm

 

1967 Corvettes with the 390HP engine would have used a single 4bbl carb on an oval port intake. 400HP engines used an oval port 3X2bbl intake. That was essentially the only difference between the 390HP and the 400HP engine: a tri-power intake. The 400HP
tri-power intake was unique to that year. The 1968 intake set lower to clear the hood.
The 1967 400HP tri-power intakes are quite hard to find. I have one that needs some work along with the 4351 engine block that is correct for 1967. The 390HP and 400HP had a 2 bolt main. The 435HP had a 4 bolt main. Of course if you're looking for one for a restoration, then it doesn't really matter because the mains are hidden and 4 is better than 2!!! The 435HP engines used a 3X2bbl rectangular port intake. The L88 used a 4bbl carb on a rectangular port intake.

The second pic of that Corvette looks to show chrome valve covers. 1967 Corvettes came from the factory with painted valve covers.
Flame away.

 

how you like them apples.........


i know where to direct my vette questions from now on.

 

The HO 327/350 came with finned alum covers....not chrome, but not painted...either way not chrome..but that is splitting hairs

 

Another tid bit about the 427 Corvette intakes. The tri-power intakes were made of aluminum and have a steel pan riveted to the bottom of the intake to prevent hot oil from reaching the bottom of the intake. Fine and dandy, but on an old engine, the space between the steel pan and the bottom of the intake gets coated with old oil and sludge and whatever small metal particles might be circulating inside a worn engine. If you don't clean out all that sludge and crud, it will just recontaminate your freshly rebuilt engine. Since the steel pan is RIVETED onto the aluminum, you have to figure out a way to drill out the rivets and reattach the pan securely. You don't want a bolt coming loose and bouncing around your lifter gallery. Some previous owner removed the steel pan from the bottom of my 400HP tri-power intake which didn't make me happy because I bought it sight unseen. Aftermarket valley pans are available from speed shop suppliers so it's not really a big deal as far as keeping the hot oil off the bottom of your intake. But on a rare intake like that one, it's nice to have every original part if possible.

 

A friend of mine at work bought a '67 triple black, tri-power 427, numbers matching, convertible about three months ago. He is waiting until spring to ship it up here to Alaska. At the time, it seemed like a good investment. Good thing he bought it to enjoy and keep, not re-sell.

 

I am not sure on which engine, but it does have a red stinger hood. He has shown me the picture from the sale and it looks great. It has the finned wheels with knockoffs, too.

I will see if he has an engine picture, which might determine which engine.

 

The tach'll tell you, too, if he has a dash pic ...

 

He said this morning that it is the 435 version.

 

I wouldn't trust any '67 big block Corvette without EXTENSIVE examination and scrutiny. A few years ago, some guys were even counterfeiting the gas tank stickers and making the sticker match the counterfeit car. As time passes and multiple transactions come and go, the history of any given car becomes murkier. I saw an original 400HP ragtop for sale a few years ago that was missing the original engine. I'm sure by now that it has the "original" motor under the hood: NOT! I also found an original 435HP coupe whose original engine had been destroyed over 30 years ago. It too probably has an "original" engine under the hood by now as well. The Corvette and musclecar world is filled with rich, ignorant, baby boomer boneheads who are just ripe for the fleecing at every big money car auction.

A quick way to tell if a '67 Corvette was originally a big block car is to look for a rear sway bar. Small block cars didn't have one. This check will usually only work on a grungy barn car because any counterfeiter worth his salt will add the appropriate rear sway bar during a fake build up.

 

A 67 wouldn't have come with knock offs. Only bolt ons that year.

And you are correct. I saw the picture again today, and it does not have knock offs.

 

Well, let's just put it this way...

I "faked" a window sticker for my 70 SS Chevelle clone. Did the sticker in PChop and "aged" it with some basic kitchen ingredients. Not hard to do. See result below. Yes, I know I spelled "emission" wrong.

A build sheet would be a piece of cake.

There were aluminum heads in 1967?

 

In 69 there was an aluminum engine option as well!

Buyer beware on the aluminum heads as well. There were/are several different variations and check to make sure the particular head is correct for 1967. There are also practical considerations. I have a 1967, 400HP tri-power intake that actually has 1969 carburetors. Technically incorrect,....but original 1967 tri-power carbs did not have a bowl vent and this would cause vapor lock problems on a hot engine. The problem was corrected by 1969 by adding a little lever and rubber stopper to cover a vent hole in the carburetor. Not original for 1967 yet probably better functionally than the original.

There were supposedly 20 L88 Corvettes built in 1967 and there was 1 prototype built in 1966 that has been discovered.

The aluminum engine 427 was called the ZL1 and was available in Corvettes and Camaros in 1969. I remember that one of the Camaros was sold new from a dealership in northwest Arkansas and, like many, the original engine was blown up and the current restoration has a replacement engine. So TECHNICALLY speaking,....not a number's matching car and not original.

Now how about the shadowy 1970 LS7 engine option that was supposedly never produced? I have a friend who actually saw one on the showroom floor and read the window sticker to verify it.

Corvette tales,.....they never end.....

 

Corvette people are a funny lot. I've owned 3 of them...

God, the Vettes I've had the opportunity to buy in the past. If I had them now, well...nevermind.

I'll try to find it, but in a similar thread about corvettes, Dave Helms posted a pic of Zora Duntoz checking out an LS-7 corvette back in the day.

I'll have to search my subscribed threads, but I think we were talking LS-7 corvettes at the time...

The Vette vues fact book of 69-72 corvettes I have (once owned a 1 owner 69 SB) lists the LS-7 as a factory option. It does not say anything about production #'s, but it's in the book.

 

Actually found it pretty quickly

Some of the comments claim it was a "crate motor"... so did it come formt he factory that way????

Who knows for sure.
