it is sweet for sure. I have not seen the build sheet but only the best parts were used according to the previous owner. He saw the build sheet, the guy he got the engine from about died after he traded off the engine for labor, PREVIOUS TO SEEING THE BUILD SHEET!!

I may have already messed up my FX trans. with this powerhouse.

part of the 20k was a three duece set up that I did not get

its hard for me to believe that an FMX could be damaged by a 390 unless its putting out well over 1000HP...... fmx's are indestructable.... my buddy has a pantera running a 351C and an FMX, car is dynoed in at 700hp and hes put about 45k on it with that fmx and it hasn't missed a turn......

the gearing would change your gas mileage either way depending on what size tires you're running.... if you running 35" tires then a 4.90 gear would bring you gas mileage back up, but if you're running say... 185/70/13 then you would want to run like a 2.73 gear to get your gas mileage up.... pretty standard tire for a 65 galaxie would be like a 235/70/15.... which you would want about a 3.25-3.50 gear for optimal gas mileage

thanks for all of the replies. I have not been able to drive it, as it in is my barn surrounded by MUD!!! I'll take it out tomorrow and check the shifting again.

I had it out for a 60 mile cruise and the next morning it would not go into drive, so I moved the selector back to reverse and it worked, back to drive and it worked as well. (although the was a 5-10 second time gap)

I had fiddled with the linkage when the engine was too far forward, and forgot to readjust it when I got the engine in it's proper place.

I may have damaged the trans by the linkage not allowing the transmission to be completely in gear. (between gears) But it ran like a scalded dog.

looking for a carb kit and vacuum actuator, any ideas?

If it's just the linkage not allowing it to go into gear, I doubt it hurt the trans at all. Like others said, FMX's are tough. They are heavy, and have some issues when it comes to hi-po driving, but they're great for street use.
