I'm gonna say whatever for this one...factory and...non-factory. What do you think are the best looking engine bays.
Alfa Romeo's 3.2 liter V-6 is SEXY.
Bentley Continental GT/Flying Spur. Those little bolts have the Bentley "B" embossed in the heads.
Of course...GM's LS1/2/6/7. They all look the same, but I like the LS7's red heads.
The Ferrari 599's V12 is gorgeous...perfectly symmetrical.
Ford Mustang Mach 1...only for the shaker hood. I like the scoop.
Ford Taurus SHO. Laugh all you want...I think it looks bad-ass.
Lamborghini Diablo 6.0. I like the gold.
McLaren F1...again, the gold. That was real 24k gold...probably the reason this car cost so much.
Pagani Zonda F. I love the car...and it's got an engine worthy of display. I love that brace.
Rolls Royce Phantom. It looks very sinister...matches the exterior well.
Spyker C8...same reason. Everything on this car is a work of art. Yea, it's an Audi V8...but they prettied it up well.
I definitely like this one for the header. Saw it in person at the Varsity.
There was also an RSX block with a painted head...looked like plates of metal bolted together. I remember seeing it on here and that paint-work looked cool as shit! Post the picture if you know what I'm talking about.
