Leaky Jeep Radiator, Ford 460 Swap - Nuts & Bolts - Four Wheeler Network

Ford 460 Swap. Q I have a 1978 Ford F-250 4x4 with a 351M engine. I just bought a 1996 Ford F-250 with a 460ci engine, and I want to replace the 351M with the 460. Will I have any problems with this swap. The company has been specializing in shoehorning Ford big-blocks into trucks for over 20 years, so we spoke to a company representative about the best plan of attack for your swap. The 351M uses the Ford big-block bolt pattern, so it will mate with your truck’s existing transmission. L&L offers engine mounts that will enable you to use the existing frame perches and keep the transmission in the stock location, so no driveshaft modifications should be necessary. The biggest hurdles with your swap are the accessory drive system, the fuel system, and the wiring. L&L cautioned that the steering box on your ’78 truck makes things a little narrow at the front of the engine compartment, and as a result there may be clearance problems with the serpentine belt system. Adding to that, the power steering pump and A/C compressor (if applicable) from the 460 won’t be the same as the 351. Because of this, L&L recommends retrofitting the V-belt accessories and accessory mounting brackets from the 351 to the 460. This... Source: www.fourwheeler.com
