hi all i m new in this site and this seem interesting! but i m a FORD GUY, i m in process of floor up restore of my 81' f250 4x4 but i plan to replace the 351M with 429 engine but the motor mount aint the same so where do i find the right motor mount for the 429 to go in my frame? help anyone? thanks

 

If you are talking about the replaceable rubber/metal mount, I would tell the guy at the parts store to go up in years till he hits a truck that had a 460. It might fit.

 

yeah, i thought of that i think 460 have the same kind of motor mounts.. but the engine i have came out of a 73' mecury marquis... but i m ll check it out but do auto parts store sells new motor mounts?

 

Go to your favorite auto parts store. For an example I went to

http://autozone.com

I entered a 73 Marquis. Apparently that year you could have a 429 or a 460. I entered 429. The left mount was #2367, the right mount was #2368. Then I went back and told it I had a 460 instead of the 429. The motor mounts came up the same.
Then I said I had an 86 f250 with a 460. They have the mounts. They are #2709 and are the same for both sides. You can find out alot on these websites now by doing this.

 

Hey is your 351m in good condition...might be interested if your willin to give it up at all

 

crazy4Fords, My son and I did this swap this past spring. Well from a 400 to a 460 anyway. We got the factory engine perches that mount to the frame. Then there are factory plates that fasten to the block its self, then your rubber mounts sandwich between these. I got all the stuff for an 83 F-250 4x4 which is the first year they offered the 460 in our body style. Or you could use the aftermarket adapter engine mounts. We used all the accessory brackets and steering pump from the donor vehicle which was a 79 E-250 van. I had my local NAPA make up a custom high pressure steering hose for the steering pump swap. Rear sump oil pan and hardware. You will need truck or van exhaust manifolds also, unless you are using headers. Offset oil filter adapter or remote filter mount, alter your factory throttle cable bracket and your in business.

 

yeah i m getting rid of my 351M it has 2 barrel right now and i have 4 barrel intake and carb i havent installed it on yet but u can buy it all off from me if u still interested i assume maybe 85,000 miles on that 351M but cant promises have extra c-6 to go with if neeeded.. let me know also forgot to add that i have brand new chrome valve cover i might include that if price s good ! thanks !

 

On headers - you can save a lot of hassle later if you go with a set of shorties. Full length headers can run into clearence problems with the tranny crossmember.

(Guess how I know???)

 

 

guess? about those shorties? i m not sure really . why shd i get shorties or the headers what shd i get for my 429? what s really any difference between regular headers and shorties?
