holley or edelbrock?

I have a Street Avenger 670 on my 360 (~370 HP). This has been the closest to out of the box an onto the engine and forget it carb I have ever had. Tried a couple of secondary springs, tweaked the choke setting and haven't touched it since. Plus it gets 2.5 mpg better than the 600 i was using and 5 mpg better than the 3310 750 I tried (17-18 around town 21-22 on the hiway) and it doesn't give up anything the butt dyno can detect to the 750, plus has the same great throttle reposne and mid range driveability as the 600.

I had tried a BG 725 Demon carb on my 360 and had problems. BG's tech line is useless and i would recomend you stay away from them just because you won't get any after purchase support.

If your car is strickly street and you are shooting for 375 HP I would go with the 670 Street Avenger over the 770 Street Avenger. These carbs are wet flowed so they actually flow quite a bit more than a dry flow rated carb. I.E., the 770 is actually a lot bigger than the 20 cfm rated difference when compared to the 750 Edelbrock.
