The quicky dyno test is a joke compared to the FTP that they are certified on. That is why they need to pass the visual and functional tests first. The sniffer test is even more pathetic. I was a Test and Repair Smog for years and have done much work fixing cars since. If you really want to go there just get the GM 50 state legal LS swap engine. That would fit well, or just take a Gen3 Hemi out of a later car and swap the whole damn thing in. WIN-WIN classic looks with a far better drivetrain. Those F bodies- and frankly ALL American made car were crap in the late 70's. Even in Cali they are rare sight; overweight, slow and no collectable value. Seems more like putting lipstick-very expensive lipstick, on a pig.
