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

29 Coupe running a SBC 400 motor with 6x2 Stromberg 97 setup, so running multi carbs isn't a new deal for me. I think most of my buddies expect me to run the blower in the Coupe, but I think she is fine the way she is. I'm pretty sure I haven't seen a blown 58 TBird running around lately so I'm going to go that route. Does anyone know, if I get a crank hub for a 390 and then build up a Mercury 410 as a specific blower motor, will the same crank hub work on the 410? I believe the 390 is internally balanced, but I don't know on the 410.
