I've been looking into getting a cowl induction hood and I've seen like two types that are either 2 1/2 or 3 in. hoods. One hood looks like it keeps inclining the whole way and the other seems to get flat on the top. This sy on ebay ( http://cgi.ebay.com/ebaymotors/1991...ryZ31838QQssPageNameZWDVWQQrdZ1QQcmdZViewItem ) has the type of hood I like, but I don't know the company or anything. I think the one that flattens out is the goodmark hood, not sure though. Any help finding out which is which?
