It is a small block.
I got the deluxe kit with 4 under dash vents and 455 cfm unit. The kit itself was 875 but being that I'm in Texas where the company is located I had to pay taxes and with shipping the grand total was 1005 dollars. I have not installed it yet, that is a project for this weekend. After reading the manual it doesn't seem to be that difficult to install. It is their universal fit system so it will not look stock, but I'm ok with that. The guy I was dealing with over the phone was Wayne Potter, 888-357-0040, give him a call see if he can hook you up.
