I'm not afraid of this flex fan coming apart. had it for 18yrs now, was on my 340 for maybe 4yrs. iv heard the stories since the 80's about them coming apart ,but have never experienced it myself. when I switched the flex fan for the electric I could not tell any seat of the pants improvements.
so, as of now I'm leaning toward the A body down flow with 1.25 2 row with shroud and flex fan. should be pretty much drop in and if the car goes into the 9's with this set up it stays, if not then it gets the electric fans and pump. project wont be finished til about 4 of july.
