Ford Racing 427 whine
Hi I recently had the new Ford Racing 427 crate engine dropped into my new BDR cobra. I noticed while accelerating that the car had a whine to it and at first assumed it was the TKO 600. This evening I lifted the hood and pulled the throttle and the whine is coming from the engine. Any ideas on what it may be?
I took a video but Club Cobra will not allow a movie to be attached.
Thanks in advance.

Belt noise, water pump bearings, what Dwight said...wide open question.
Get a length of heater hose, hold one end on a part (like water pump) and other in your ear. You'll find it right away. For the belt, spray a bit of WD while it idles and see if it stops.

You probably have gilmer pulleys. How wide is your "fan belt"?

Gilmer belt. I'd include a K&N filter for that price 
Get a better shot of the pulleys tomorrow to be sure. Unless your riding on the fender in that video your transmission has nothing to do with that sound. |

Had a corvette make the same sound. After changing the waterpump with no change in Lise turned out to be an electrical noise caused by the alternator.

Thanks for the input guys. I will take some pictures to post tomorrow of the belt/pulleys. From behind the wheel I would have sworn in was the TKO.
Interesting on the alternator MADMAX, would not think this would be the issue with a new alternator?
Almost sounds like a blower

Ditto.....loosen or remove the belt. If the noise goes away it is one of the belt driven accessories. Most likely the alternator.  |

You got the narrow millerspeed "gilmer" pulleys. So the sound is "normal". We install them when people insist. |

Thanks for the help Jay, the previous build didnt make the same noise so I'm assuming they didn't put the gilmer pulleys on that one.
Two quick questions:
1) Why do people insist/request these?
2) What do you put on for people like me who would rather go without the whine! |
