Hey 76maveric, this is your conscience speaking. Are you allowed to do that? I know in some states cars over 20 years old don't have to pass a smog inspection, but are ya able to blank off the egr port?
In New Zealand, we ripped off all the smog gear Australian cars were saddled with and it would gain about 5% on some of the more efficient cross flow Falcon six engines. They never ran air pumps, thank goodness!GM Holdens had gastly air pumps as well as EGR, and you'd get another 20 horses using no smog gear, EGR and run 4-6 degrees intial advance instead of 9 on the crank. I think the cam timing was retarded just to get past the smog tests too, so there was extra performance on useing the earlier settings. It was worse than in the States with Aussie emission engines. There was no unleaded gas and simple cat back exhasts, so the emmisions equipment was not as advanced. There were no fuel control or 3-way catalyizers until unleaded arived in January 1986. It was air pumps and EGR's to US 1973 specs from 1976 to 1986.
