I'm trying to wrap up a SBC conversion in my FJ40 (retaining the 4 speed), and I was wondering if anyone knows if I'm supposed to still use a stock Cruiser alternator or now go with a GM one. Also, do I need a different fuse box too? I've had some wiring problems, and rather than buying a whole new harness I opted to just take out the stock and go through everything, while also eliminating what I don't need. Any advice would be great. Thanks!
