Just look at the back in the showroom here, pretty rough, and what we're getting into here today is this. one, the Grand Sport Corvette, has an LT 4 engine, I think he said around 750 horsepower and I mean it's a two thousand three hundred pound car somewhere in that range.

Doug and we are getting into the

lingenfelter

Grand Sport, so it's based on this is 67, is it 6363? You know, Carol came out with the 289 Cobras in '62 and started killing Corvettes on the US road racing championship circuit, right? aura Duntov wanted to return with a cobra killer, but what happened was done upstairs. He went to the GM dungeon and had the skunkworks project for the Corvette Grand Sport. This car is actually 7/8 scale so he made it small enough that I say weight but people wouldn't notice so it's 7/8 scale of a 63 bet and then he proceeded to make the body as thin as paper.

sport

, I mean it is, but you know what I mean, it's like it's a really modern modified version, well you also have modern wheels and tires, so I mean, you do it with suspension like Well, there's also an improvement in suspension to deal with what you're doing.

The suspension is actually an original suspension. It has some adjustability, but you have the transverse leaf spring. You can opt for a modern carbon crossbow if you wish. but it comes with a steel leaf spring, okay, and then the standard front suspension we changed the front geometry because the original cars had the turning radius of a battleship. I mean, you know, racing cars weren't built to beat you, of course, and so on. However, we use that Weiser wood, it's a Detroit speed power steering rack, there's such good stuff from Detroit and then we put in the radiator that comes with the rolling chassis, so we have a radiator here that's big enough to to cool a large 572. -block or whatever you want to put, yeah, look, but literally any GM small block, big block, whatever you want here, yeah, so are these 17 here 17 front bullpen rear wheel drive teens with real knockoffs, just they suck on all of our cars, but we also offer it with a 15 inch fiber wheel that the car originally ran on, both aluminum and if you want to be really old school magnesium, it's a good option, I mean, if you really you want to try to stay pure. to the automobile era because this is a car that you can't, I mean a 63 Grant Sport that you probably can't get, it's probably almost impossible to get, yeah, it's only five of the originals and they're all in museums.

Um, yeah, Simeon has one in his museum, there's one in the Florida museum. I'm not sure where the rest are, but when I think of three coupes and two roadsters, it's like Jim's version of the Daytona Coupe, you know Shelby made six of the original Daytona Coops, the cabinet on this car is so comfortable with the tilt steering wheel that you know it will do with the base full racing interior, yes, but most cars were also ordered today with the Touring interior because it really does. for a really nice and usable tram, yes, well, with the old air conditioning, you will freeze outside the car, yes, that's what you're saying, we're about to discover this heat today, yes, and it's all glass the entire bodywork.
The body glass is okay, it's funny because a lot of the original Cobras were a bit much, so they would go up to the deck on the replicas and say it was aluminum, you know, and they would do it in bed and I was like They were all fiberglass, right? Okay, it was easy to keep the original, yes, easy, although we used a much thicker body than Duntov used, yes, yes, that's just why the car you're not racing, I'm telling you, buddy, a one of the coolest things ever, it's funny that it's Both on the Cobra and this one I'm a big fan of the side pipes, it's so nice that tone right there, yes it really is, and the sound that this lt4 With these side tubes you will like to hear nothing you have ever heard before. from a new rear zo6 this is really nice here and one of the best things compares to the original 63 vets so yes you have the package tray in the rear yes it is good for some things yes but We actually have the back part. a trauma, so people say wait, you know, the original big

sport

s that I wrote, the original vets never had a trunk, but now the big five sports had an access panel back here to access the rear suspension on the back. rear to service the cart during a race, so the guys turned it into silver, oh, we turned it into a trunk because obviously it's not necessary and look how much we wrung it out, well, we have Shelby pillows here, but look, I mean, It's quite deep, yes, we can trace it, of course, between this.
In the parcel tray you can do almost anything, yes, amazing, now how is this? Let's say this exactly if someone says I want to buy that car, what is this car? So, one ninety-two blows my mind. How much do you make these cars? which are actually reasonably priced for what you're getting what I love is that you guys stay so true to the history of each of the vehicles you deal with, whether it's the Cobras or the GT forties, the big sports cars , the Daytona coupes that I love. that you guys are, you can say you're in it, it's not like you just left, nice car, let's make it look the same and then put everything else and you in the car and you're actually trying really hard to stay. faithful to what the car was, yes, some respect, I mean obviously this one makes it a little more radical.
I always thought they were kit cars and replicas, they aren't just so you know there are many other companies that make kit cars. making replicas is not what you guys do, so it's time to go driving, what do you think, let's do it buddy, that's a lot of car, that's a lot of car, that's a lot of power. I walked away from my car effortlessly, guys, you got a lot of brakes, didn't you? What are the brakes? Will they be electric disc brakes? What's your redline here like 6500 ish and you'll see it will depend on your engine because that's why there's no red light mark because you can put any engine you want on.
I want who there will be different red lights so you can come in with a pushrod engine, you'll be on the red line, you know, a pushrod small block at about 1500, six thousand, right, I like that this engine is accelerate until you know, the climb to the north. God, just keep everything, Napoleon is not going to stop 750 r. Right now I'm sitting at just under 4 and I can tell with a roll-on that there's so much stuff, man, at 4500 or comically. It has a lot of torque and they go into the superchargers, but it's surprising, it's funny because I've talked about it with a group of my friends versus the superchargers.
Sure I like a bull, but I'm a forced induction guy, but I prefer supercharged ones. cars I like them, I really like the grunts again, very sold, that was good guys, that's it for our photo shoot of this incredibly cool Grand Sport Corvette. I mean, I barely got into it. I mean, I'm talking a little over five thousand dollars. and this car just pulls and pulls and pulls and feels stable and planted to the ground. I mean what these guys do, if you haven't noticed I've become a big fan of top performance. I am completely impressed. for what they do and how generous and cool they are to let me drive their cars, so I hope you had fun in this episode, you should know that I'm having a lot of fun with this stuff here and while we're down here.
