Thinking of buying a Street Demon Carb...

Edelebrock has the "Thunder series AVS". That would be direct Replacement-ish?

I was originally leaning toward the Thunder Series AVS until I saw the price of the Street Demon yesterday, but after reading some of the talk on the Demon, I'm now rethinking the idea of getting the Thunder Series AVS.
I just looked at the Holley HP Series on line and I see that none of them have a choke, so they are pretty much a race carb. My 340 is bone stock. I'm looking for something a little tamer.
