SBC rods are also too narrow to use on a 6 cylinder crankshaft as well. Scat also makes them for the 194-250 engines. There are a good variety of aftermarket rods for the 194-250 engines, so you don't have to try and use something that isn't designed to work in them. For the difference in cost to modify SBC rods, it will be of no benefit to do that since there are many choices for rods that bolt in with no other mods required.
