Re: Factory 402 cam specs - desktop dyno
Why wouldn't I use closed chamber heads? I assume mine are open anyway, but when I hear "don't do what the factory made millions of for almost a decade", my ears perk up.
I probably will select a different cam, not because I think I'm smarter than the factory engineers, but because cam technology has actually improved in the last 40 years (though it might take a hydraulic roller to really benefit).
There's pretty much no amount of cam that's going to make one of these trucks fast, so I prefer that it's got a good idle, good vacuum, good cold-start driveability, and so on.
