300 to 460?
Hey,
I have a 79' Ford F-150 with a inline 6 4.9L. I have a rare chance to get a 78' 460 out of a Mercury Marquee for FREE. I have a few questions for yall to answer for me. Since my truck has a C6 tranny on it already, will the C6 on the 460 fit with the driveshaft? Will the driveshaft be too long/short? Will I need to replace the radiator? What about the rear end replacement, will I need it? Is there mounting brackets for the 460 since the 79' came with a 460 option? I am generally looking for anything I should find out before I attempt at installing the 460. Thanx and yall come back now...

79monster, You will need quite a few items to do that swap.
1.) 460 frame and motor mounts ( L&L Products sells kits, as well as P.A.W.)
2.) Heavy Duty 3 - 4 rows Radiator / shroud.
3.) 351M/400 - 429/460 C6 Transmission.
4.) 460 Exhaust System.
5.) Believe Drive Shaft has to be shorten.
6.) All 460 Pulleys and brackets (even Power Steering Pump).
unless you fabricate your own.
7.) Heavy Duty Front Coil Springs.
8.) And the little nuts and bolts that comes with doing a swap.
Your 9" Rear a fine as is, unless it's already in bad shape.

I have some info that might help. I am taking a 460 out of my 1977 f150. I have almost everything you would need except for the exhaust. I am looking for some parts to put a 300ci straight six in my truck like the tower motor mounts, throttle cable, clutch/prake pedal with linkage and mounting bracket and the radiator? If you have these parts still I would be willing to do a trade if you are not too far away from Washington state. I would pay to ship the parts to you if you could ship the ones I need to me. Just let me know what you need.

Dont get rid of the striaght six. If it is runing well id keep it, repair it if u can. I have one in my f100 and its a great motor, if u try to go over to a 460 its gonna be a pain in the rear, and most likly not worth your trouble. Id get a hold of another truck to do this to. But if it were me id keep your current motor.

fatman_11:
Could you give me the ~CORE~ measurements (not including the tank sizes) for your radiator? I'm going from a 300 to a 460 and www.radiator.com has sent me two radiators that are the wrong size. Is the opening for your 460 radiator in the mount that it locates onto 24" X 18 1/4"?
The core size of the radiator I have in the F100 now is 24" wide by 18 1/4" tall --- they keep sending me radiators that are 24" wide by 27" inches tall (core size!!).
Anybody already been through this?....
