Engine transplants have been around since time immemorial. After all, if you have an old classic with an outdated powertrain, wouldn’t you want to keep it up to date and give it something that fits more to our times?

Raybestos Garage certainly understands this thought. That’s why they took it upon themselves to take a 1964 Pontiac GTO-R, one of the most iconic American muscles in history, and give it a modern powertrain make-over to the tune of an LSX 454-powered 700-horsepower modern-day maniac. Raybestos and Hot Rod Chassis & Cycle used the frame from the ’64 GTO-R and added a few noteworthy parts, including a GM-sourced LSX crate engine, a Tremec six-speed manual transmission, a Moser 9-inch rear-end, custom fabricated body and suspension, $20,000 Raybestos NASCAR brakes, and a reverse-sweep 180-mph speedometer.

After all the work done on this American beast, we’re left with a 700-horsepower machine that, get this, is being given away for free by Raybestos! That’s right, you can drool over this car and have it in your garage in as easy as a few clicks. All you have to do is sign up for the contest on Raybestos’ site and you stand a chance to win a one-of-a-kind classic with a modern twist. We’re still trying to figure out what’s in it for them, but it may just be the crazy amount of advertising the group is getting for this contest alone.

There’s also plenty of videos detailing the build of the car and some behind-the-scenes looks at how this tuned-up workhorse became the head-turning monster it is today.

UPDATE 08/11/11: We’ve updated our video line-up of this monster-infused Pontiac GTO-R with some more tidbits on how the car is doing! Give it a watch, folks! It’s mighty interesting, to say the least.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More

They really dissect that car to place some engines that will fit to give better or yet best results.

It’s attractive, and that’s because they themed it into a retro taste. I see it that it has styles and can be one of the fashion items for this modern day.

Its retro-modern look is what’s made it attractive. Its performance is only essential to the appealing senses once you’ve seen it run with style.

The unique detailing of this Pontiac car is the reason why this is called the most iconic American muscles in the history. This is a one of a kind classic with some modern twist.

Its old classy car still can give entertainment and speed fast your looking for a car. And I’m really impressed with the speed performance of the car . The produced power is just enough to me .

I really love the old Pontiac style and now i saw this 1964 version with a modern power-train make-over, I wanted to see how it drive off road.

I’m really impressed with the speed performance of the car. I’m not really in the styling of the vehicle. The produced power is just enough to me.

hmm. Ever since the styling of the car haven’t change it still look so vintage. However, with all the old cars, the Pontiac is one of the few that’s so interesting. I’m really impressed with the performance of this car. I would say that this is such an iconic vehicle.

Opposite to what you are saying Ashton Blake, the tuning of the car is very important for every automaker because it their way to upgrade their car and can also be the beginning of their new versions.

I’m not really fond of a tuned car, which is already as old as my grandmother. It doesn’t make any sense why they are reconditioning this kind car, though they can create a new version.

That’s what I called better rendition. A car from the 60’s is almost vintage. But Raybestos Garage give a new look and power to this hot rod. I really love when a car from the late days comes up with a new power and appearance.

The market really shows that there are still some people that wants to drive a conversion kit of a old classic. I’m really concerned on the engine performance of the car and with the power output of 700, I bet its engine would be reliable.

I think they have customized the exterior of this car and I would say that it looks sportier on that styling. I can see on how Raybestos Garage has been so fascinated with the conversion of Camaro to a modern Pontiac Firebird. The speed performance of this car is quite impressive for a muscle car.
