Quote: For factory stock, I think the only thing they will check is that you have acceptable vacuum at correct idle setting. I wonder if they they would do a tear down for class certification unless you are protested??
I'd expect that unless you are trying to get the car Certified (it's voluntary), there's something of a "don't ask, don't tell" thing going on re: how "stock" some of those cars' cams are.
However, given the constraints outlined by the rules above, I could still spec out something using modern lobes that should be worth a few ponies over the OEM cam of yours we measured.
I know it bugs you that Bob won't come up with the specs to his cam, but as far as the rules go:
Lift and duration as well as adequate vacuum is the only thing tested. Several cars that have been Certified under the rules (voluntarily) run Bob's cam.
Is there something modern out there that has factory lift, duration and gets 16" plus vacuum? I don't know. What I DO know is that Bob has run a 12.09 and Jim has run an 11.97 using that cam and that is good enough for me.
