according to an article in GMHTP
stock intake--222.45cfm
accel intake--251.51cfm
stock runner--203.17cfm
accel runner--242.02cfm
stock intake & stock runner--198.72cfm
stock intake & accel runner--213.52cfm
accel intake & stock runner--215.83cfm
accel intake & accel runner--232.53cfm
From what I have heard Edelbrock is the same as Accel on flow but have not seen any numbers and TPIS is just an Edelbrock intake with port matching and TPIS name and higher price.
As far as runners I think everyone here agrees AS&M semi-siamised runners flow the best out of the box.
hope this helps
