I normally hang out in classic tech but I just bought an engine, T56 and IRS unit from a 2003 Cobra which I intend to put into a 67 coupe project. The engine only has about 31k miles on it so it should be fairly fresh. One big drawback for this swap is the weight of the DOHC engine. I am considering buying the FRRP 4.6L Aluminum block for supercharger. Can I essentially swap all of the parts from the iron block to the aluminum block? I would of course install new bearings and rings while I am at it. I also assume there would be some machining required before the block is ready for assembly. Has anyone done this swap?
I think if the new block has knock sensor bosses they'll have to be ground down so the intercooler will fit. U.M.
bosses Ford has taken care of the bosses on this particular block. Per the FRPP site: M-6010-A46SC Latest generation aluminum 4.6L block Features chilled bulkhead casting process for a stronger main web and bulkheads Round main web windows reduce stress areas for potential failure Ball burnished 17mm-thick main caps for strength and rigidity Machined for 2003-2004 Cobra front dress, will also fit some 2-valve front dress from iron 4.6L blocks Knock sensor mounting bosses eliminated for use with supercharger applications
SWEET! Sounds like that block is the hot ticket for your build then! U.M. P.S. Since you will be swapping everything over to the new block go ahead and replace the pistons while you're at it. They are the weak link in the reciprocating assembly. Get a good set of CP or Diamond pistons.
