Local shops got a deal on a set of Flowtech's he ordered in for a project that went away, big block b-body. My research not coming up with many positive results for Flowtech. I'm using Doug's in my small block a-body, fit perfect. I don't know anything about the Flowtech for a 440 b-body. I'm inclined to stick with Dougs but the price on these is really good. Any experience with the Flowtechs??


Oh yeah, it's a hybrid.....it burns gas and tires!
