yeah, but here is an extreme case:

you buy a v6 camaro, register it, get it insured. then swap in a V8. If it is still registered and insured as a v6 and you cause an accident, say speeding through an intersection, killing someone that thought they could pull out but you were going to fast..

the fact that you changed the engine in the car and the added speed killed someone gives your insurance company the right to not cover the accident. Since you killed someone, not even going to criminal charges. They can then sue you for everything you could hope to have, if your parents paid for the car/ are also listed on your insurance for you young guys, then they can sue your parents for everything they have. In most states, if you don't have enough money, you can also go to jail.

So why not tell the insurance you swapped a v8 in it??


im not saying it let them know about every little bolt on, but some people are more careful.
