What are the various state laws (Virginia in particular) regarding EGR on SBC in older cars with titles dating before the emission rules? Not only is the Edelbrock Performer-with-EGR more expensive than the Performer-without-EGR, the performance looks to be less with the EGR. What is the policy regarding retrofitting a SBC in an earlier car that is titled before the '70s and the engine came with an EGR unit? How careful are inspection sites regarding engine serial numbers as to the date of manufacture and emission laws?
