You're better off buying from Indy through a a dealer. Todd Marsh (Marsh Performance) always gets my vote. If there's any issues he can put them right or work with Indy to correct. The KB block is considered to be the ultimate but the Indy Block can work very well too. It's a lot easier to get a Indy Block at the moment.I wouldn't hesitate to use another one but I'm not the guy who goes for (or can afford) a 2000+ HP motor and chassis to match build laugh
