FE Technical Forum / 390 crank key-way size question.
« on: October 08, 2015, 02:39:57 PM »
Is there a standard size to the 390 crank dampener key-way?  Or am I forced to pull all that off the car to measure it? 

I need the size of the key-way to order a blower crank hub from Hampton, or any other supplier.

Thanks

FE Technical Forum / Advice for running a 671 on an FE Motor
« on: January 09, 2015, 01:29:45 AM »
So, we have a Mercury 410 motor and a few 390s from 65 TBirds. 

I am supposed to be getting a Weiand 671 with FE intake and dual carb hat.  At this point I don't know which FE intake it is, or which generation of 671 either, but I would like to start gathering information if it does happen. 

I believe the 410 is the best motor to build for this, and we should go with forged pistons, but beyond that I am outside my knowledge base.

A local motor builder I know tells me we will have to run alum heads or we will have lots of detonation problems.  Is this true?

Also what cam would work well. 

We also have a 6x2 top for the Weiand, so we might decide to try and run it with the six Strombergs I have, or the Holley 94s.

Thanks for any help you guys can give me.

Cheers
Bryan
