I have a stock 75 L-48 engine with a performer intake with a cross over. Fel-pro has way too many options. I find one and then scroll down to the comments and it says to a buyer your better off with this part #. Go to that part # and says to that buyer your better off with this part #. So I think I have 3 choices. Part # 1256 or #1204 or MS90314-2
