Look up your carb on summitracing.com. You said "4150", I'll assume List 4779.

Suggested parts include brackets, studs, return springs, kickdown levers, fuel lines, etc., etc., etc.

I believe it is 1/2 NPT.

Re: track guys help

I ran THIS a few years back. Works awesome!!! I still run the plate actually just for the throttle cable holder, but it came in handy the other night when i installed the nitrous solenoids, i mounted the regulator back up where edelbrock had the provision for it. nice unit..spendy, but it looks nice and clean and works like a champ!!

This was a few engines ago, but it gives you an idea of what it looks like on the engine:
