My 422 smallblock build

yellow rose likes the 260/260. Ed Hamburger , the old 340/360 guru said for an automatic (aka slushbox) go like 252/260, for a stick (or a gearhead car) go 260/260. Ed was cool to talk to, way back when he said ld340 intake, then Offy portosonic, then victor 340. I run his modified 340 windage tray etc.
