regal and 455

when i get a new job so i have money, i plan on finding a 80's regal, and puting a olds 455 in it.

I was wondering what is the best year that i should try to get when getting the car. I'm not going to worry about the engine condition, just find a good body with no rust, and a good drivetrain.

i have a friend that had done this to his regal, and i liked it so i want to get a "toy" lol, just not as nice as his.

thanks
