You can get the street avenger in a 670, 770 or 870 CFM. I run a 770 CFM on a 383 cu in motor. The only difference that you will notice is that the 670 is just not quite enough if you turn over 5500 rpm. Holley has a chart on their web site. Physical size, and connections are identical on the entire series. Holley just increased their price to $435 if you get it from them. You can still find it from Jegs or Summit for $390 or so. Won't be long before they up the price too.
