Original Style Alternator
Anyone install an original style alternator (C5TF-10300-F) on their ERA with an FE? Any issues?

I think that is the type/style suggested by ERA.
What do you currently have?

I have the Delco part number called out in the manual which I purchased the NAPA equivalent. I was looking for something that looked more original, I don't like the one I have that is cast in chineseium...

This article may shed some light on your issue
Shelby & FE alternators
I put a 45amp 1G on my first car and found it often 'discharging' because the alternator couldn't keep up with the amperage requirements. Went with a hybrid on the second build. 100amps and most people can't tell the difference from an original

Hybrid? Is that a 1G case with 3G internals? |

As I understand it, the main case is the Ford 1g. The rear of the case comes from a GM vehicle. With that, they're able to pump out 140 Amps. Take a look at the Tuff Stuff site for more details and info
It will fit an FE, depending on the heads used. Clearances get pretty tight

I have a Powermaster 7078, which is a 75A direct replacement for an original alternator. It works well in my ERA with FE.

Forgot to mention that getting the original style alternator fan is the real tricky part...

That's the one I was looking at... the 55A is all I need. What was tricky about the fan? Also, did you have any issues with your belt alignment? |

Craig did the installation so I cannot comment on the belt alignment. We used old school Ford pulleys and I do not recall there being an issue. My understanding is that the original BB cobras used a high-performance pulley / fan on the alternator. Finding that was not easy.

Now that I think about it, Craig may have made to make a spacer for the pulley. I am sure if he sees this he will comment.

Thanks for the info! I take it that the pulley and fan from that site are not the correct ones?
Hopefully Craig chimes in... |

I do not believe they offer the correct fan/pulley for a cobra. It is almost impossible to find a reproduction, never mind an original...

Figures, well it is what it is. I don't have an original Cobra so I'm not going to lose sleep over that. |

Yes,
They are had to find. You can use the standard single sheaf pulley from a T-Bird (63-64) or Lincoln of the same vintage. The last N.O.S. large diameter pulley we had went for over $600.00! Dearborn Steel Tube did a run of repops some years ago for the Thunderbolts, etc. but they have dried up. We would entertain doing a run if we could sell at least 50 units at somewhere between $100.00 and $150.00.

This is with the smaller diameter pulley which we have some original, used units. We also have the round case 1G alternator cores. |

I would be in for one of those if you find enough interested and decide to make a batch. |

The alternator pulley on Kevin's car required a bit of work to get everything fitting, I had to squeeze every bit of clearance I could to pull the alternator back towards the engine block.
Both the water pump and crank pulleys need to be spaced accordingly to the alternator pulley.
It all worked out great on Kevin's car with enough clearance on the shock tower etc.

Definitely the piece I had the hardest time tracking down for my build.
