360, LA360, or Magnum 360?

I was going to build my early 360 but got a killer deal on a 91 with less than 4k on rebuild. have to say i like the way the roller cam revs. Even with just the rebuild it has plenty of daily driver power I've walked away from a few wanna be racers already lol. Some of the parts are off my old 360 so it don't look as new as it is.

Good feedback here! Thanks!

Any guesses as to why it might rev better? Does it have a lighter crank or lighter pistons?

How many RPM can you turn on the stock bottom end on Magnums or LAs...is there a big difference here?
