85gplef41, the whole point of buying a erod is to keep a car emission legal which is why one pays a premium price for it instead of purchasing a much cheaper but illegal to install junkyard LS or a plain new ls motor. Another concern is tinkering with the engine internals would probably void the factory warranty which is part of the premium price. The erod package is a drop in and forget setup, it isn't intended for traditional hotrod tinkering. If you don't like it, don't buy one and stfu.
As for bigger fish, governments have always preferred small fish, softer, weaker, and easier targets. Laws are like webs, they only catch little things, Chinese proverb.
Nascar and hotroding has a dubious past starting from illegal bootlegging and rum running. Many early Nascar drivers were criminals running moonshine to avoid taxes as their main source of income, not something decent people would look up to. Hotrodding has a long history of dishonestly, and shady practices such as street racing that has killed innocent bystanders. Frankly if you don't like emission laws, then start a movement to repeal such laws. Attacking and insulting me and playing internet tough guy does nothing to repeal the laws you despise so much, they merely make you look petty and butthurt. A real chatty Cathy.
Erods are not normal production engines like in new camaros, two very different certified packages. Even with new camaros, it is still illegal to reflash the ecm as the government considers it tampering. Newer stuff has more restrictions, every new model year they tighten restrictions more and more. Lastly the op lives in Cali where emissions enforcement is much more strict than what you are used to in Co. The level of enforcement of the laws varies from state to state, with southeast states being the most lax.
As is, a stock ls3 makes 30 more hp than a mint g body was designed to handle and it would likely cause a major failure in a crusty g body. The op should be concerned that his frame and body are up to snuff and that he doesn't have a unsafe car. Being a Cail car it should be in decent shape unlike the Co rustbelt. Still he probably will need new body bushings, and frame and body braces to withstand that 430 hp safely. If you want to risk your own car, money, neck, and skate out on the thin ice of legality, fine, but telling others they should skate on thin ice too because you like it is wrong and negligent of you and makes the whole lobby look bad.
Reality is often not present, and I rather be a so called Debbie downer than a Ostrich with my head stuck in the sand. Laws and regulations governing automobile setups is a Elephant in the room discussion that is too taboo for some gearheads and gets their panties tied in a knot. IMO, I think it is silly to treat the subject as some awlful taboo.
