427 original style pulleys?
Where can I get some original style pulleys for my 427? I see them on eBay all the time, but don't know which ones to get, double crank pulley or single?
Will any 390-428 steel pulley work?

What accessories are you running? If you're just running a water pump and alternator, you just need a single crank pulley, a water pump pulley, and an alternator pulley.

So long as you don't underdrive them, and so long as they align properly, "Yes." |

Forgive my ignorance, but what do you mean 'underdrive' them?  |

Then keep it very simple and do it like I did. Here is a picture:

You do not want your water pump pulley to be "underdriven" in order to save horsepower. That will cause you to overheat. Plug in "underdrive" and "water pump" for a search and you'll find many, many threads. The most recent one, as I recall, also included some pics of some very nice pulleys from the Kirkham bros. -- I think I remember that, but I could be wrong. It was a very recent thread though, like just last month. |

Nothing you see there is fancy. The balancer and pulleys are all Jegs stuff, as I recall, and not on the expensive end either. The water pump is an Edelbrock. You don't need to spend a lot on this type of stuff -- it's the stuff that goes on the inside that tends to cost a bit more.  |

Underdrive pulleys....running the accessories slower than the crank by diameter reduction. Gains a few hp.

Hi-Tech,
I have some info for you if you're still looking for original Ford pulley's. I sent an email to you a bit ago. Just found some yesterday and there's more parts there for an FE as well.
Look at your email and we can go from there.

I think a stock pulley will work but it is hard to tell by the pic. If you like I can get a measurement from something for you tonite . I see the stock pulleys on ebay fairly regular. T

I have an eldebrock water pump and I believe the same ati dampener that you do.I am using march pulleys with a stock ford fe alternator and mounting setup .My top pulley belt groove is 5 and 5/8th inches to the block measured from the machined flat just over the passenger side water pump port to the center of the pulley v groove.
The lower pulley measures 3 and 3/8's inches from the center of the v groove to the flat between the mounting bolts on the stock timing pointer.
I also measured a different engine on the flloor that has the same water pump but all stock steel pulleys,all measurements are identical.
I hope this helps,I'll be glad to take pics if you need them. ,Tim
