Hello all, I am hoping someone here can help me 'cause I now have tried everything that comes to mind and quite frankly i'm losing my mind. I have had problems with my monte starting lately. I just recently put in a mildly built 400sbc. I noticed the factory 66amp alternator was giving me problems due to the flexalite electric fan I installed (draws 18amps). I replaced the alternator with a brand new 105 amp high output alternator and I am currently running a brand new optima red top battery, new starter, new distributor (timing is set correctly). Here's the thing, it still won't go. The volts show it's charging and there's plenty of power there. When I go to start it, it wants to go but will not completely turn over. It had turned over a dozen times with the 66 amp alternator before the alternator needed to be replaced cause it was draining itself dry. I have checked all the electrical to the battery, the posts, alternator & all connections, starter and distributor connections. I have also checked the belts. Everything appears to be connected and in place. The car has a half a tank of gas in it. Anyone have any clue's as to what the problem might be? Any help or suggestions are greatly appreciated! Thanks much.
