4 valves per cylinder

Well I was thinkin about how much I would love to have 4 valves per cylinder. I know on diesel engines they only have one cam, but they have 4 valves/cylinder. But they have bridges to push both the valves. If you have worked on semi trucks then you should know what I am talking about. I will try to take a picture tommrow at school of an engine with bridges.

Nope, they didn't come out with a good 4v V6 until like 2004.

here or some pictures.

So Cliff you say not until 04. Was it an OHV?

Nice pic of the cummins 24v. My cousin has one of those.

I don't think GM has made a multi-valve pushrod V6. Only DOHC ones. The 3.6 is the most successful attempt at that.

damn, just think of the horse power gain. I have been looking up this thing on google for the past 3 days and nothing but OHV.

Just a shot in the dark. would those heads work on 3.4L?

Making your car 4vpc would be pointless. I'm not going to say its inpossible but your looking at alot of$$$$ probably in the 10k range and for what alittle bit of rpms? Your dollar to hp ratio would be like 200 to 300 per hp. You can make good power with 2.8 3.1 or 3400 with 10k.
If you want 4vpc try to stuff a 3.4 dohc in the car.
Just my 2 cents
