Just picked my motor up yesterday from Bartons.
Has an 8-71 stepped up from a 6-71 a few years ago; did spin slower and made less heat.
Also when I spoke to Indy about their Modman intake they told me that it would be the limiting factor in my motor; and that I was better off using their dedicated blower manifold and porting my Indy SR heads to match. Needed an intake that could accept injectors for my Fast XFI system on this motor.
