I disagree with your unsupported conclusion--- a fuel injected blower motor like the HP700 will run circles around an ILMOR and deliver power in the heat and altitude a lot better than any naturally aspirated motor.
As for reliability the HP700 is a work horse type platform and reliability is phenomenol. The only issue is perhaps a little more attention to maintenance than a N/A motor ie...blower oil changes and belts.
I will take a fuel injected blower motor all day long if I bought this platform it would definitely have a set of blower motors.
P.S. Plus the resale is better and you can upgrade the HP700 to a Whipple stage one or two and really put up some numbers.
P.P.S. Still waiting for a GPS photo of the speedo!!!!
