big-block conversion
I'm trying to swap a dual-carbed 460 for the stock inline-6 that's in my 86 F-250. Any tips, tricks, or trouble hints would be greatly appreciated. I have 3 big blocks and no where to put so i figured i would stuff one in the truck and then use the 300 I-6 for an airboat project.

That body style had 460's originally form the factory. So some stuff from the junkyard should make the swap possible.
Of course you know the bellhousing for the six is different than the big block.

I think the mounts that the motor mounts bolt to are the same but the trans from the 6 will not match up to the 460. You need to double check that to be sure any way just some things to look at

I used the tranny mount from my I6 to mount a 76 460 with c6 in my 1980 F-100. but I built motor mounts out of both the factory I6 and 460 mounts to where they needed to be. But if you can find a truck with 460 it should have the motor mounts you need. I had looked at L& L but it was just too expensive.

Are the mounting perches 460 specific or would they work from a 351M or a 400? I am asking because I am considering putting a 460 into an F150.

No, the 351M 400 perches will not work if you use the factory 460 engine mounts.
What year of truck might you be working on?
