The guys at American V8 Classics and Customs have come up with a rather unusual approach to making big power. Instead of fitting their 1969 Camaro with a big, powerful engine, they have fitted it with TWO big, powerful engines!
I ran across this car at SEMA 2013 and spent some time admiring their work. What you are seeing is not a mirror: there are two 427cid V8 engines under the hood of this bad boy! The transmission tunnel has been lengthened and extended into the passenger compartment to accommodate the second engine, which is directly behind the first.
With a combined output of 1,200 horsepower, this car is treading on supercar territory. Each of the aluminum Grimes “Twister” engines puts out 600 horsepower and 595 lb-ft of torque, which in itself is pretty cool. The fact that there’s two of them makes the car even more interesting, but it also creates some unique engineering challenges.
Each engine has its own oil pan, so a simple oil change takes 13.5 quarts of oil (6.5 in the front, 7.0 in the rear engine). Cooling is also an issue. To solve this, Jim Walker of AutoRad came up with a custom 2-in-1 radiator and six electric fans to keep the engines from overheating!
If you want a car that’s different from everything else on the road, American V8 Classics and Customs in Alpharetta, GA would be the guys to call!
