Another 351m/C6 to 460!!
 
Well I decided instead of building a 351m I was just going to go big. So I'm going to buy a re-manufactured long block engine from a place in Texas. I want to use my C6 that I have. I need to know what I need to do to get it swapped.

This is only a street truck so I was going to go with these motor mounts.
460 Mts.351-M, 400 Bronco, F150, F250, F350

Also heard when going through the swap threads that there is something you need to do to get the torque converter to bolt up to the 460. If someone could explain that to me that would be great.

Will the Distributor, Valve covers swap?

Going to need a power steering pump bracket if anybody has one?

Well I have all the parts for the 351m still so anything that will swap over would be good to know.

Any opinions would be great.

Thanks in advanced.

valve covers are not the same, I don't know about the dizzy, someone else can inform you on that. What's your plans for the engine?

JB78f150 01-23-2012 11:02 PM

Just going to be a stock 460 with a 4 barrel carb. Anybody else got input?

The dizzy will indeed interchange.

Early model 460s, something like late 60's-72 have larger diameter crank pilot than the later models. The later model 460s (i think 73-...) have the smaller deeper crank pilot that the 351m and 400 also have.

JB78f150 01-23-2012 11:11 PM

Cool, anybody know about the torque converter?

thekingofcows 01-23-2012 11:17 PM

The crank pilot (at least that's my redneck term for it) is what the snout of the torque converter centers on.

If the 460 is an early model it will have a fe sized crank pilot. If it is the later model it will have a the same size crank pilot as your 351m and you can use the same torque converter.

The same year they swapped crank pilots, ford also began externally balancing these motors.

Do not use the flywheel from your 351m. It will bolt up i think. But it will not work.

JB78f150 01-23-2012 11:19 PM

What fly wheel will I need. Got a part number or link to summit?

thekingofcows 01-23-2012 11:25 PM

Depends on the year of your motor. With that info, I think you'll find it quite easy to look up on rock auto or summit or wherever.

JB78f150 01-23-2012 11:28 PM

Ok I will have to find out. I am trying to get the engine in the next couple weeks but we will see how that goes.

This occurred mid-year 1979. The block casting number is D9TE-6015-AB

This engine uses a weighted spacer. The harmonic balancer and flex plate are specific to this casting number which was used thru 1997.

D1VE-6015-AB is the block casting number for 1971/73 429's, 1971/78 and some 1979 460's. Does not have a weighted spacer. The harmonic balancer/flexplate are not the same as used with the D9TE block.

D9TE: Since this "running change" occurred mid-year 1979, there is no before/from certain serial numbers or production dates. The casting number must be known to get the correct parts.

Passenger Cars were not available w/a 460 after 1978. Ford did not offer the 460 w/4WD or w/a manual trans until 1983. 1968/82: C6 only.

D1SZ-6375-A .. C6 Flexplate-Use with block casting number prefixes: C8VE, C9VE, DOVE, D1VE.

D9TZ-6375-A .. C6 Flexplate-Use with block casting number prefix: D9TE.

You should send me your 351M. :D

Good luck with the 460 swap!

🤔 so if I were to run an externally balanced flex plate on a 73 Lincoln 460 would it give it a nasty knock at idle and make the crank pully look like it's about to fly off?....

The 351-400 dist. will work.

you will have significant vibration issues. that will eventually cause bearing failures and other expensive problems
