HP500 Vs 525

Whats the difference between theese two. What makes the 525 so much more desirable then the hp500. Efi engines also inject the regular 502 efi in here as well.

The 525 has aluminum heads and closed cooling and a Motorola computer. The 500 has cast iron heads, is raw water cooled and is also no longer produced. Eddie

I thought 525's were naturally aspirated.

the old 525 was blown. the 525 closed cooling system is great. if not in your budget, then send the 500efi to innovation for a upgrade to 525 specs, and she will have more torque than the new ones. we have both.
