megablower

The MegaBlower is 19.55" and a 6-71 is around 20" from the front of the gear cover to the back of the bearing cover. If you have access to the MegaBlower, perhaps bring a 6-71 base gasket to get an idea for a mounting plate. You might be able to use Indys 6-71 plate and just need to drill and tap new blower bolt threads, as the MegaBlowers bolt pattern is narrower than the 6-71. I would try to expose as much of the MegaBlowers discharge port as possible, as the 2 lobe blowers don't like restriction. The twisted 71 series rotors aren't affected as much by a restriction.
