The only issue is that you need a double pumper carb. The under the carb NOS shooters do not require this however.

Top shot nitrous
I've been wanting to install some nitrous in my car for a while, but i just can't fit a plate system under the carb.... not enough clearance between the filter and the hood. I only plan on doing a 75 shot. Anyone here have experience with the top shot kit? It seems like the best bet for the amount of power i want to add and the challenges that face me.

You have to be using mechanical secondary (double pumper) carb to use the top shot system. A vacuum secondary carb (quadrajet) will not work because the secondary air valve will not open fast enough and you will be spraying gas and nitrous on top of a partly opened air valve.Not good.

Just a ponder...
I've looked at them as well, but for the moment I'm thinking I'll keep the quadrajet
