First off, the engine bay in my Rambler should be wide enough, if the engine at it's narrowest is 27"... but then I have the problem of the charging system.. The rambler currently has a 32A Motorola alternator, which I'm not even sure could run the 4.6's electronics, let alone, the A/C, cruise control and other things it will have after I'm done.. but what kind of alternator could I run? I don't think the stock 4.6 ford alt will like the ramblers wiring harness. I know the rambler can easilly be hooked into a GM 3 wire alt by changing some wires around, but can I get a custom unit that will fit the Ford mounts, and be a GM 3 wire?
