    From what I could find they range from 750hp to 1000. Imagine what a tuner could get out of 27 liters of engine.

    At least its not this. Hold on to your hat old schoolers [​IMG]

    What is that thing??? At 1st I thought it is a V12 Detroit... but I don't think so. I had several of them years ago and don't remember what they look like exactly...

    Wiki: The 702-cubic-inch (11.5 L) V12 "Twin Six" was offered in United States GMC commercial trucks, and as a special order option in Canada. It was often mistaken as two V6 engines welded together but in fact was a single casting.[1] It used four separate exhaust manifolds, two separate carburetors, two separate distributor caps driven off of a single distributor drive,[1] and other parts from the 351. 56 major parts are interchangeable between the Twin-Six and the other GMC V-6 engines to provide greater parts availability and standardization. It produced 250 net SAE horsepower (190 kW). Torque was 585 lb·ft (793 N·m) It was used in small cab over trucks and large hd pick up trucks.

    That at least makes a little sense. I was thinking it was a diesel at first but with carbs on top and the way the exhaust is, it didnt look right for a diesel
