What Carb for Poly Stroker

Well I've been driving for 2 days now with the new carb and I'm happy with it but surprised as well.
I was expecting great low speed, part throttle response with the smaller primaries, but it's no different to the Holley. However, give it the full beans and it's definitely got more torque. On the first run yesterday I punched it on the highway in D at about 60mph and after a momentary bog it took it off so fast I thought it had kickdowned into 2nd.
Today I did a few short runs of about 10 miles after fiddling with the accelerator pump arm (putting it back to the center hole from the leanest setting I did have). Not much difference, so I put it back to the leanest hole again when I got home and tightened the secondary flap screw slightly. Haven't tested this change yet.
This is basically "out of the box" with only my rudimentary adjustments during some very hot (95-100° weather), so it's clearly got more to give.
One big plus - on both my Holleys if I got on the throttle heavy I would always smell the engine in the cabin.
With this Edelbrock, I can go full throttle and no smell at all.
