Projects My 61 f100 302 aod swap !

Use a cable for a c4 with c4 gear

 

Will it work with my original speedometer ? If it does is it possible to change just the gear at the trans side to a c4 23 tooth ?

If you get the cable that has the right thread for the speedometer and the other end for a c4.It will work. The gear for a c4 will work. You might need a different tooth count to calibrate the speedometer.
I forgot to mention NAPA should have a catalog showing cables by ends and lengths.

 

Thanks for the help I'm going to give napa a visit, I much prefer them over the other guys as far as auto parts. The calibrating part is what has me kinda stumped.

If speedo is too slow you need less teeth if too fast you need more.I don`t think there are more than 23 teeth.

 

Omega speedo from speedway motors, GPS unit from Jegs, looks like an ordinary speedo, just has the little 1 inch square gps receptor on the dash

 

Hey I am doing the exact same thing a 1964 F100, for the placement of your engine what measurements did you use? I want to make sure I have ample clearance on the firewall.
Thanks!

 

Honestly i dont have a measurement, what I did was place the motor in with trans attached and pushed it back as far as a could to the firewall to where it would still clear my trans tunnel. Once i had it in place I used bolt on mounts and just slid them into place where i wanted them and spot welded them into place. I thought it was a hell of a lot quicker that way because once they were spot welded in I just took the motor out, drilled my holes from the inside of the frame out, and bolted it up and the motor fit like a glove.

 

Thanks for the information! I****ume you pushed the motor as far to the passenger side as you could? Did you have to shim behind the motor mounts to the frame? i notice with mine there will be a bit of a gap.

 

Why push it to the side? Mine is dead center in the frame

 

To align it with the differential, everything is off to the passenger side slightly. This is information in received from my mechanic and my father in-law who is a license mechanic and Ford Nut.

 

I'd do a lot of measuring before I "pushed it to the passenger side as far as I could" Dead center has me doing just fine.
