There is a magazine article I read about putting a 4 barrel intake on 2V motor. Use the 2V gasket, bolt on the intake like normally would, put a nice 650cfm on it, and an instant 30hp improvement. My friend has a 71 torino 2V that we did that too, and what an improvement. We didnt use the Boss intake, but a 4V cast intake and it ran awesome. Just a thought.
If you have access to Ford Performance book by SA designs, on page 96 they have a little write up on it too. they said put a 780 Holley for a quick and cheap 35 hp.
