The Ford Falcon is done and heading up to an event in Leeds. The Australian 250-2V cylinder head has gone on with a new exhaust manifold and a custom made twin SU inlet manifold for the two 2″ HD8 SU carberettors. Simply changing the cylinder head and the carburettors has given a 34% improvement in BHP. That is a huge gain and just goes to show how bad the original log intake cylinder heads really are.
Ford Falcon treated to a new cylinder head
Mike Haigh’s Ford Falcon is getting treated to a new cylinder head. The standard cast iron cylinder head found on the old Ford inline sixes has a terrible port and inlet arrangement with a ‘log’ type manifold cast onto the head. Back in the day the Australians got wise and cast their own heads with a separate inlet manifold and a standard 6 port arrangement. The head is otherwise identical and bolts straight on. It only took a year to source the rare Australian 250-2V head and get it shipped to the UK but it’s here, it’s been ported, polished and has big valves. We’ve machined a divider for the central siamese exhaust port and once it has been skimmed will be fitted to the bottom end. We are all taking bets as to what it will be worth in BHP.
