My first GT40 build. Got the engine (302) in and now working out how and what alternator to use. Space is tight so have ordered a single groove March crank pulley to keep things back from the bulkhead. I am looking at getting the alternator low on the right hand side on a purpose made bracket. A Wosp 300 looks as if it will do the job. I am thinking 95amp but there is a 175amp equivalent. Even with electric power steering pump, electric vacuum pump and all the usual fans etc I can't really see the need for 175amps. What do others use?
