Holley has an Excellent Intake, good heads(equivalent to GT-40 Turbo Swirls) an a piss poor cam. 350 hp I am kinda weary about that claim!!
Edelbrock has a great Intake(Performer RPM), better heads, and a good cam. 337 hp Probably fairly accurate....more accurate than Holley's claim.
With the SystemMax kit being cheaper, I would get it, port the heads and get a good cam, then you will have a for sure 360 hp ride.
