YOu don't need a lot of valves if you don't need to go over 9000 rpm (since 2 valve street pushrod engines have been known to rev that high with regularity). You don't really need a lot of bandaids for replacing low end power like variable valve lift and timing of you start with a larger engine.I like DOHC better... You have room for as many valves as an OEM possibly wants to put on the engine & varriable valve trickery is simply insane. It's also a hell of a lot easier to service.

You mentioned the Viper
8.3L - 500hp.
Saleen S7
7.0L - 575hp
I still don't understand exactly how the DOHC motor operates without pushrods?...I will try and re-read this thread and get a grip.. I grew up only working with big pushrod V8's. I never ventured into the smaller DOHC motors...Never took the time to learn about them...Are they worth while? I do understand the Dohc motors rev higher which would be better suited for the smaller motors to produce more power...
Are there any DOHC V8's?
