I would use the nitrous so infrequently is why I was thinking top shot for ease of installation, to save a few bucks and the hood clearance issue! I do not need or want a 400 HP application, just a 75 - 100 HP shot now and then!!

Then it sounds like the Top Shot is what the DR. ordered.

The idea 2 posts above about the 2 fogger nozzles in the plenum sounds interesting. I had not thought of that way to install a system.

The only question that remains is will a top shot fit in my aircleaner! That is the question that i need answered if anyone has a top shot system! How much space do I need between the top of the carb and the bottom of the aircleaner lid! There are no dimensions on the Holley website!

You don't really even need that. Just take a spray bar from a plate system and drill and mount it in the intake just above the plenum area an inch or so below the carb.
Yes,it will be much cheaper also.

The other good thing about the top notch is that it can be hidden real good .

Thanks for the advise all!! Eric, I have considered that and wondered if it would work!! Great thought!!
Has anybody just installed the spray bar into the intake plenum??
