429/460

You will like the swap.  I have a factory "N" code 1972 Gran Troino Fastback.  I ran the 71 heads and advanced the cam 4 deg (not the timing).  This brought the compression up to 10.5:1 and gives me the stock 1971 output of 360 hp.  As for your swap, most of the info has been spelled out already, but you will have to replace the C6 from your small block to that of a 351M/400, 429 or 460.  If you do not want to spend the $500.00 on hooker headers then look for a 1972/1973 Thunderbird with a 429/460 motor, it will ahve the correct exhaust manifolds that you will need.  These are very nice units and flow good too.  I would also run a larger radiator.  With this motor I got 16/17 mpg with a 2.75:1 L rear end and P-245 60 R-14 tires.  I would also recomend running an electronic ignition from a 1975 or later vehicle.  I use the factory ford pieces teh 351C/351M/400 and 460 all use the same electronic ignition.  Be sure to get the wiring harness that comes with the distributor and Ignition module.

Have fun 

You will also need a nwe trans. Even though yours is a c6 it is for a small block not a big block. Your trans crossmember will work but you will eather have to shorten your drive shaft or get one from a 72-76 Torino/Cougar?LTD with eather a big block or a 351/400 modified becuase they use the same bolt pattern as the big block trans. Good Luck.

Also i am working on my second 1972 torino swaping a 400M for a 460. the only thing that i needed to change was the motor mounts and springs

oh an a large hole in my hood so my stealth intake would fit.

1. The 460 I got from a 71 lincoln was rated at 425HP and 500 footpounds at the flywheel, so those numbers do not sound off.

2. In never took My Four door Torino to the track before the engine blew up(one of my greatest regrets), But i know from street encounters It would beatup pretty well on a friends mustang that runs 13.9. Iwas using 2.75 gears, C6, 460 with dove-c heads, a Weiand stealth intake, 750 holly double pumper, and a Comp 270H cam. I mild setup with no headers, MSD, high way gears and the extra weight of the 4-door car. however I never used the 460 with stock componants since i got it from salvage.

3. when the tires tilt in or out it is called camber. On top of your Upper control arms under the hood are 2 bolts, loosining those will allow you to change the camber but i would recomend that you take it to a professional shop to get a front-end allignement to save tire-ware

amen to the tired of bodywork... I have along time to go when till i rebuild my 460..this is what i have been doing for th past 3 months.

So the tranny that i have in my car is probably a C6 then? I know its a 351M but i just used the code on the door to figure out my tranny size, maybee it has been changed to the C6.I was supposed to pickup my engine today but there was a delay so i hope i can pick it up tommorow!!! I will be putting an Edelbrock 600CFM carb on it that has been sitting in my dads shop for a while. Will that be enough CFM for the motor?

When I first built my 460, i had a 600CFM Holly. when i got on it around 3000RPM i heard a whistleing, sucking noise from my carb over the sound of the enigne. The engine just seemed to have no power after 3000. But i used that 600 for about 2 years without any trouble. Finaly a friend gave me an extra 750 Double Pumper. and that helped abit. upto about 4000, but i think why the power seemed to level off there was due to my stock exhaulst manifolds and no exhaulst porting on my DoveC's.

My 2 cents is that a 600 is definaly too small for any 460, but I will work until you are able to find/afford something bigger.
