twin gm 3800 on a 392 ????????

[remcolent]

I am playing with the idee of using Two eaton m 90 superchargers on my still to rebuild 392 in my 57 imperial
this becouse I don't want a 6-71 with carbs and scoop 2 Ft above the hood
I run the engine on propane so only trottle body needed
as propane is a high octane fuel I am thinking of 10 to 1 compresion ratio
with only moderate 5 to 8 psi boost
I like the m90 becouse its more efective than the big 6-71
and only use a small beld to drive the supercharger
I need low and mid rpm power
I have the tools to make a custom low profile inlet manifolt
is this a possible good setup or is a 6-71 tho only way to make power
Thanks
