Other than the 5% increase in hp and closed cooling,is there any benefit to the 525 powerplant.I see used pairs of 500s' for 25k and 35k for 525s'.Is it worth the 10k for closed cooling and 50hp(for pair)?thanks Mike

Absolutley! The 525's are a much better engine. Closed cooling (biggest plus), aluminum heads, sport tube headers etc. The 525's usually put out around 540hp where the 500's put out 470hp.

Thats a great sugestion!! Aluminum heads and a computer recal and you have more than 525. If your not in salt water, I don't really see the advantage of closed cooling. My 500 EFi has performed flawlessly, but I'm up here in cool water, For what thats worth.

And what about the 575 SCI ?Do they have problems that would make you want to stay away from them? After all they were built only a few years before they went to the 600 SCI with whipple chargers.thanks guys,Mike
