Anyone know the belt sizes for a standard 318?

I can tell you mine, not sure if 318 and 360's are the same. Mine is also a 1975 with 360's and Sherwood single pocket raw water pumps and use a NAPA number 25-7430 for the raw pump and a 25-7459 for the alternators. Hope this helps, still have the old ones?

If in doubt, take the belt to NAPA (or another GOOD auto store) and they'll match it up for you.
