Re: GMC V12
These engines are notorious fuel hogs in stock low rpm form....
I imagine they are crazy thirsty when modded to spin twice as fast...
I love the idea of large engines and the vehicles they stuff them in but the "Twin Six" was always a somewhat impractical engine that was phased out by the rising popularity of diesel... It was a so so truck engine, makes me think it would be a so so hot rod engine...
