There is nothing special about the 575. Just your basic 502 with a very marginal blower and injection setup. They need lots of attention. I believe you could upgrade your 500s, make more power, spend less money and be happier.

I now have a pair of Paul Pfaff 700's that use the 500EFI intake setup and they run great. I love blower motors, but I am very happy with these NA engines.

I have the build sheets if you are interested.

You'd be better off to Whipple the 500efi's.

I have a pair of 575's built right now running 700hp and love them.
They are a good motor if you put a few $$ in to them. (Roller cam, open up the heads and remap the computer and they easily make 700hp)

I have 2 spare 575 blowers if anyone is needing. I went with new TBS replacements this year.
I already had them rebuilt once but probably ready again.
