Do you think an intank 255lph is sufficient for a 347 with 36 lb injectors, TFS intake, cam, TFS NOS system? I also have an inline 255lph, with seperate pickup, that I can run simultanousely but was told that would be more than the stock return lines could handle. Opinions please!!
I'd just run the inline in front of the intank. I have ran a single 255lph with a 250hp wet shot, but that was on a stock shortblock with E7s, not a built 347. I wouldn't worry about the stock return at that level.
