Thanks for telling me that our cars have a DOHC setup, I wouldnt have guessed it. Now, a 3.0L V6 DOHC vs. a 5.6L V8 is quite different. Its a much larger engine. From the far point on the VK56DE exhaust valve covers is roughly 31", where as the VG30DETT is roughly 24" at the same point. And as he pointed out before, a pushrod V8 is a hell of a lot narrower. Hence my terminology.
