'67, L-88, Tanker???
 

Is this car real? I didn't know this combo existed.

I may be wrong but I don't believe any L88 had a radiator shroud :toetap:

Did you get the VIN?

Mitch

Only two N-03 options were installed in MY 1967. It's probably reasonable to assume that both went into L-88 Coupes, but I believe N-03 was available without restriction (other than it could not be installed in a Convert), so you could have ordered a base engine/PG Coupe with the big tank.

It's also my recollection that '67 L-88s had no fan shroud from the plant, so it was probably added, later. The combination of no fan shroud and no vacuum advance will cause the engine temp to get high, fast if idled for very long or driven in low speed traffic.

Also, that "560HP" SAE gross rating was with headers and open exhaust and massaged heads. With manifolds, mufflers, and as cast ports, the output was much less - probably not much more than a L-72. The valve overlap is specifically designed for headers and open exhaust and is WAAAAY in excess for manifolds and mufflers. They were built with an OE type exhaust system so they could be shipped and moved around prior to delivery, but it was assumed that the owner/racer would install a suitable racing exhaust system.

The '67 435 tri power ex-road racer I had was dynoed at 550 hp at the rear wheels on a chassis dyno when it raced back in '72. The only mod was headers and open exhaust. Heads were untouched.

Is there anyone that repops the big tank and rear inner fenders? That would be killer to have on cross country road trips!!

I thought the tank was coverd by a rubber mat or something like that. the other big tanker car was at Carsile about 10 years ago. I belive the guy in OK owns or owed it. he also has a couple of rare cars

Use these pictures as a reference. Kevin McKay did a full restoration on this car.

Duke, I believe that one of the NO3 cars was actually a white 350hp coupe. I see no mention of GM documentation on the L88 so I would be very carefull with that car.

Okaaaaaaaaaaaay... What was the air density correction, and what were the revs. OE cam! Untouched heads!

Nowadays SAE net conditions are used for typical rear wheel pulls. Way back when it was standard sea level conditions, but even with this correction, you're talking about 650 at the crank, which is about what a 510 Can-Am engine with Kinsler IR injection could pull - maybe a little more. At 6000 revs that's nearly 570 lb-ft of torque, so the peak would have to be least 630 lb-ft... from a naturally aspirated 427 with 11:1 CR... I dont think so!

Your memory is playing tricks on you. Maybe the 550 came from "factoring" the RWHP back to the crank, but even that is high. In OE trim with manifolds/open exhaust a good L-72/71 might make about 450. Headers will help, but not more than about five percent because the cam doesn't have enough overlap to make best use of exhaust wave dynamics in the upper third of the rev range.

I've never heard of any legit. research that has verified exactly which two cars got the big tanks in '67, but I think there must be about double the 20 factory built '67 L-88s "claimed".

I would be suspicious of any L-88 that didn't have multiple factory or other documentation (like published articles) that corroborated authenticity - seems that many have suddenly popped up after having been "lost" for 30 years. Yeah, right!

Duke

The car is obviously a fake. The "real" ones had the passenger side wiper blade on the "top". :lol:

If I'm not mistaking all 63-67 corvettes had the passenger side wiper blade on the top.

Good eye! I missed that. This car appears to be freshly ahhhh... "restored", and that's one detail they missed!

If you look at any C2 AIM N-03 Section you will see that there is a cover that mounts in the rear section that should hide the tank and fill tube. This cover is obviously missing in the photo - maybe to display the details of the big tank that the OE cover hides or maybe...

Yoooo, Jeff! Where did you take these photos - a dealer? Museum? Can you provide some more details?

Duke

That shroud is supposed to be there-remember it was "LOST", now it's re-installed. Only Big Tank '67 L-88s had the shroud. ;) I saw this one in person, so I know it's correct. :yesnod:

The dynoing occurred before I owned the car. The numbers came from the previous owner who was the one who raced it at Riverside. In retrospect, I agree that at a minimum, this was probably corrected to the crank. Just going by his memory.

I do know that everything internal was OE, since I obtained the car after it was retired from racing and it still had the original motor, untouched till some kids stole the tri-power.

In a Chevy dealership this past weekend. Just the local clubs once a year car show. I was just taken aback because I didn't know what to think. There were a lot of beautiful cars but when I saw this L-88 I didn't know what to think. If this car is real I'm really lucky to be looking at a museum piece or just a very good copy. Still don't know what to think. :crazy: Hoping someone on the board knew more.

I love the classic car shows at a Chevy Dealer. The local car clubs hold a show in a brand new Chevy dealer near me. Its one of the best shows all year. :thumbs:

If you really wanted to know more about this car, you could probably contact Kevin McKay. If I'm not mistaken, I believe he has a registry of all L-88's created from the factory.

assuming, of course, that this L88 was created by the factory . . . might need to sneek a peek at the VIN in order to reference the car properly, as Mitch has already suggested.
