Help me finish designing my 440 build. 1973 Scamp

The Torker 2 would probably work okay. I've never used one of those intakes but they are probably fine for what you're doing. The Sniper will control nitrous but I haven't used that function in my own car yet. If you are going to go with a power booster you should make sure that your fuel pump can handle it. I have the Aeromotive 240 pump and it barely keeps up with my engine on the dyno. I'd need to upgrade my pump to run nitrous.

The torquer 2 can be worked to flow about like a stock victor for a r/b, w/ only about 25 cfm scatter between the runners. A professional could probly do better ! It`ll probly flow w/ ur stealth heads unless u go far out w/ them, altho it doesn`t quite keep up w/ my heads, but I can run a 14x4 1/2" filter w/ it under a 6 pck scoop.
I run one w/ a f.inj. set up, I did have to go to a wider lobe separation cam for the f.inj. tho . JFYI
