I'm anxiously awaiting it's release. I called Holley in December for more information - the guy I spoke with didn't have much info.

I also tried to find out what the ARCA spec fuel pump is. The Ilmor efi 396 spec motor puts out 700+ hp. The guy at Ilmor gave me a specific contact at Holley, but I have yet to get him on the phone.

Things I want to know:
-what is the ARCA spec EFI pump
-will the hydramat cause any vacuum at the inlet of an EFI pump? (most efi pumps list 'gravity fed' as a requirement)

I need to make some fuel system changes. But I'm not changing anything until the hydramat comes out.
