how to title car in MN

[MnCCX]

Hi,
I am purchasing a 1988 contemporary classic cobra equipped with an original 427 FE side oiler. The car was titled originally in Florida as a 1988 but have been told that I may still be able to title this car as a 1965 b/c of the motor. When I called the MN DMV they told me that if it was originally titled in MN they could look at the car and probably change the year of title but since it was titled in FL they could not do that (they wouldn't question the year of title issued by another state). Somebody has advised me to tell the DMV that I just put in this motor now and try to get it titled as a rebuilt car...does that make any sense (I'm also not too excited about the lying part in the first place)?

Does anybody have experience or ideas of how I could get the car titled as a '65? I ask for future resale value and b/c it would save me money on taxes. This will be my first Cobra so I am as new to this as you can be so any advice would be appreciated. Thanks
