Stock Big Blocks in A bodies

Thanks for all the help. I can't change insurance companies as we only have one government one here in British Columbia. I can insure the car at regular rates, but if I can get it to comply with their definition of a "collector car" (which includes an engine size produced by the factory) the insurance goes from $1500 a year to $265 a year. It doesn't sound good for me though....... Thanks again for all the input
