nitrous carb adapter
I am mounting a Holley 4165 spread bore carb to a performer RPM square bore manifold and am wondering about adapter options. This is for a 89 Firebird, so hood clearance is an issue.
As I want to run a small shot of nitrous, my preferred option would be to use a nitrous plate as the adapter, but do not know if one exists.
My second option would be to use a phenolic carb adapter, but again cannot find one.
Ideas welcome...

Re: nitrous carb adapter
you run a normal holley nitrous plate and would run a spread bore adapter on top of that for the carb, although without a cowl hood this will not be possible. Easiest option is to sell the holley and buy a 4150 style carb to fit under a stock hood.
