Variable Valve Lift & Timing, sounds like a pipe dream, especially for our 30+ yr old motor design, eh?
Well, maybe not, I had a brain fart the other night and started drawing stuff out and talking with a few knowledgable people and I think I may have come up with a way of having VVLT on both intake and exhaust valves, that is infinately(sp?) variable and independant of eachother, only REALLY expensive part would be the computer to control the whole system. I am going to do some patent checking and what not to see if this sort of thing has been tried before, in a few more weeks perhaps, I'll let you know.

WHO would be interested and how much would you be willing to pay??
(I just don't know how much it would end up costing for all the parts...)

P.S. this is not a cruel joke or anything, it looks like it can really work, all I need is a bit of time to get it together.

The price people would pay depends on the performance gain.

are you talking about like honda's VTEC system. if thats the case than you would need a dual cam setup to run intake and exhasut valves and you would need 4 valves per cylinder.

No don't need DOHC to has VVT. I don't think It can be done to solid lifters. L series doen't work good in extreme high rpm anyway because, one, turnflow head, two, it looses lash pads, and three, bottomend won't handle over 7500rpm unless you got full-counter crank.

VVLT for the intake and exhaust would be very hard to do with a single cam. im speaking from having experience with Honda's VTEC using their single and dual cam applications. on the single cam you only get variable lift and timing on the intake valves because you cant fit that many lobes on a single cam, that is why i said you would need a DOHC for VVLT on the intake and exhaust valves.

V8 or turbo.. or both - easy, bloody fast, and cheap.
