Car insurance on Hemi swapped cars

I just had an agreed value policy with my regular insurance (State Farm). Didn't treat it as a classic car or anything in particular to my knowledge, just a regular car with an agreed upon value. Granted mine isn't anything like a show car, it's a pretty straightforward modern drivetrain swap in an otherwise "normal" car. I've also got several other vehicles under policies with them, and our agent at the time was really easy to work with since she knew we were a car family.
