Watching an engine up on a stand doesn't always count as porn, although Lingenfelter's 358ci LSx flat plane crank race engine with a 76mm Garrett turbo, producing more than 1,000 hp. Watch for it in the Lingenfelter Gen V Camaro SS.
John Hennessey's got this great shtick going where he takes his Frankenstein monsters and pits them against stock versions of cars we associate with performance. It's total nonsense, but how the hell do you not watch a twin-turbo Cadillac Escalade race a Nissan GT-R?
Chevy gives great head... cylinder head, that is. From the LSX small bore to the LS7 and LS9, Chevy runs deep in cylinder heads in this lazy susan-like display at the 2010 SEMA show.
