Holley Street Avenger 670cfm to big for 318cui?

I have a 300ish HP 328" (.060" over 318) in my pickup, and I ran a 670 Truck Avenger at first on it. It ran fine, but I got a good deal on a 570 Street Avenger and used it on the truck, moving the 670 to a big block (mild). The 570 did the job fine for years, then I sold it to a customer for a 289 Mercury Comet I built and put a 625 Street Demon with the TQ-like plastic bowl on my truck. I like the Demon best of all, but I think with a 4spd in a light vehicle you'll be happy.
