Looking to upgrade the alternator on my 360 since the old Motorola one from 1971 doesn’t seem to be cutting it.
I am running fuel injection and associated ancillaries, dual thermo-fans and soon to be CSR electric water pump. Thinking around 140 Amps and internally regulated would be the go. What are people using and how do you have it mounted. Doesn’t look like the factory bracketry will work with the CSR pump. This is primarily for drag racing so lots of battery draining short runs. |

Good info there.
Looks like it is a chrome Aeroflow brand a GM/Delco 120 Amp unit then, pretty much the cheapest thing available on Aussie eBay without getting into used parts. Should get the job done. The only other thing i want to do is to hook up a relay to the ignition terminal on the starter solenoid to turn off the thermo-fans while the engine is cranking to save a bit of juice. Oh, and upgrade to a mini-starter.

A Delco cs130 from an 89 Pontiac Safari is an easy install. By cutting an inch off the back of the pivot base it will mount the same as the Motorola.

Pretty sure the one I ordered is an updated version in the 10SI case and will do one or three wire hookup as needed. With the electric water pump, I won't be able to run the Motorola brackets, so will have to make something up anyway.

Ha! sockets make great spacers, plus they are chromed to match.
Looks nice and clean, like new even. |

Never mind the sockets, you should try finding a 7" long x 7/16" UNC bolt on a public holiday.

Ah, that I understand... ended up using a head stud for my custom setup. |

With that much amperage you will want to consider running power to a new fuse panel to run the hi current draw accesories. I am running the same style 10si (100 amp) internal regulated. I ran a #6 wire to the relay and then to a Painless wiring junction block which feeds the 10 circuit underdash Painless fuse block and also the factory feed to the original fuse panel. The junction block makes it nice as I ran out of room on the relay post as you can see as the Robb MC starter feed needs to be on the hot side of the relay |
