While Most Americans never gave the 6 sylinder a second thought as a performance engine. It did not help that Ford USA short changed the 200CI engine with an integrated log intake that really starved the outer cylinders and made the 6 cylinder asthmatic.

Down Under though, the cylinder was never discards as such. In the mid 70s, the old head was given a big make over with an intake made for a 2V carb that had runners to all the carbs. This is basically a bolt on 40HP (or about 50% of stock BHP) for a 6 cylinder engine and puts it in the range of a stock 65 289 2V V8. For more history of the Aussie 250/2V, go here.

The Oz 250/2v head and intake fit in a 65 mustang with no modifications, except for convertibles with the extra bracing. The carb will have interferance with the extra brace supports as seen below. My way around that was to go with a tower brace kit.

Upon receipt of the head and intake, I had the intake and exhaust valves enlarged to the maximum size that would fit. The valve guides were also replaced to fit US spec valves incase I have to replace them later. I also had the intake modified to accept a 4V carb to get better overall performance. Currently I am running a Holley 4150 390CFM Carb.

The head and intake received from Ford Six Performance Parts were in excellent condition and at a very reasonable price. The only problem is that there is a long waiting list and the supply is dwindling as there were only limited numbers produced.

NOTE: If you head has the stock sized temperature sending unit port, it is important to note it is smaller then the stock 200 Sending unit. I found that a 64.5 260 V-8 Temp Sending unit fits perfect.
