If you junk it then be sure to save that double groove lower pulley and the single plane two barrell intake manifold. Those pulleys are harder to find now and those intakes rock if you like two barrels. I have also used the larger 360 two barrell intake and larger Holley carb on 318s. If it is an early LA 318 it should have #675 head which are woth keeping as they dont have the air holes under the exhaust port. If you decide to rebuild it for racing you may want to upgrade the connecting rods to 75+ 318 or 360 rods. All 318s got the bigger rods in 1974 I think.
