6 Pack vs. 650 4BBL?

Should have no problem having some fun. Yeah, I know Demon is a Holley product, but there are some pretty ugly reviews right here on FABO about them. Personally, I've never bought one.
Here, right now on FABO....
I'd take the 650 DP in this post.... or either one of these two would out perform your carb
[FOR SALE] - PRICE LOWERED----Holley 670 street avenger & Holley 650 DP
Or the 770 in this post...
[FOR SALE] - Holley Avenger Carb and Nascar Fuel Pump
or just a good ole' fashion 750 dp holley.

I actually bought one of the 625 demons when they came out 3 or 4 years ago, it is a nice carb, took care of my heat issues.
They do have one drawback, you have to dissemble the carb to put the mopar throttle linkage on, and the stock linkage will not work, you need to buy the one in their instructions.
