I know cobras and mach1's are 4v and gt's are 2v. But what does having 4v mean compared to 2v? Meaning the differences between the two besides a difference of 2v. Before i even ask that question what is 4v and 2v. I know it has to do something with valves, i think. Someone enlighten me.

Each piston head (8 of them, one for each cylinder) has an exhaust valve and intake valve on a 2v motor. The 4v motor has 2 intake valves and 2 exhaust valves. Having 4 on each piston head allows some better breathing at higher RPM for higher hp. That is why GT's have a little more low end grunt than the 99 and 01 cobras down low, but the cobras pull harder, smoother, and longer up top. Hopefully i've explained this correctly.
Since you are in california, or anybody else that is from california. Where can i find good deals on engines. I am trying to find some engines in this area, so that way i can save money on shipping costs. Any one know a good place??
there are probably places out there that have engines, go with a reputable company , even if you pay shipping, you will get what ou pay for most of the time. Truck freight is not that bad.
does anyone know flow specs on the heads for both the 2v and 4v. i was reading that the new 5.4 flow 350cfm with the 2 intake valves. thats pretty sweet.
