525 has better rods.
The rest is primarily in the fuel system and camming.

Either way you have a very sound base for Whipples. Both are excellent motors, with all the best pieces in them.

The alum heads make the 525 an excellent candidate-less worries about detonation= more potential boost.
HP500 EFI is probably the best bet cost wise though. I'm not sure of the $$ difference, but I'll bet it's substantial. There's a ton of these engines running with Whipples too. The Whippled HP 500 EFI makes close to 800 ponies. Either way, the Whipple is AWESOME.
