Hi Guys

Im running a modified 302 with 4SPD with a Stealth Manifold. What Carburetor
would you recomend & what would be a good size. 570 & 670 or 625 with
demon.

Thanks

You can never go wrong with an old tried and true favorite like the 650 dp. I haven't had any trouble out of my 670 avenger YET though and other than getting ready to bump up the squirter a size its been pretty much a bolt on and go.
 
i ran a road demon 625 for quite some time, never had a problem, and was a significant improvement over my holley 4010. i switched to a holley 600dp 4150 that i modified for blowthru supecharging. if BG made a demon for blowthru i probably would have bought that vs. modding my old holley. i'd say you can't go wrong with either the road demon 625 or a holley 600dp.
 
i have a road demon 625, absolutely hate it. either that or i got a bad apple. it get way lean when the secondaries are partially open. that would be the secondary transition circuit and theres no way to tune it.
