I bought the car with it on there.... 

The whole set up ran great.. but the 460 and the 385 series just didn't grab me.... But if ya want to go fast.... there is NO substitute for cubic inches....  That 460 sure pulled like a freight train.....
gosh..I wish I could remember the company that made that dizzy.....

Old saying....two ways to go fast, cubic inches or cubic dollars.....

I got ALL my stuff from Restoration Specialities...... a great guy name Matt was a fantastic key point man..... 
I can't say enough about them... they had EVERYTHING and more......

What are we going to do with that AC-DELCO electric on that engine? ...

One of my 57's had a 460. a fine engine..... it was tight but no work on the cooling system.. no fabrication what so ever...
it ran super fine.. the only reason I changed it to a 428 was of heritage... but when it had the 460... it ran cool as a cucumber
I believe it was a early 70's vintage.

  Everything mentioned is pretty much spot on. Biggest obstacle is the cooling system and you'll have to trim the radiator support for at least clearance for a bigger radiator and maybe a fan clutch. I also used Crites headers that fit great but made my own solid motor mounts. I really like the 460 platform for obvious performance potential. Would I do this swap again? Absolutely!

I have a 460/C6 in my '57 Custom. It was installed using Crites mounts and headers. No modifications were needed to the trans tunnel. The radiator support was modified to move the radiator forward for fan clearance. I later added power steering and air conditioning. It has been a generally successful installation. Would I attempt it again? Nope. Crites is out of business so mounts will be a problem as well as headers. The 390/428 route as stated by others is the easiest route to more power.

In my opinion an FE series engine is the "only" way to go. The parts can be all factory since the FE was first factory installed in '58s which are practically identical. I put a 390 (from a '62 Mercury) in a 57 Fairlane in 1967 as a 17 year old with self taught driveway mechanic skills. I have had several 57s with 390s a couple of 428s and my current Custom has a 462 stroker 428 with a tick over 500HP/550 Torque. It is too much power to drive in a way on the street. Just saying!

Both of my '57 Couriers had 352 engines...and they were bolt in jobs. Same as a 390. Easy,and done in one day.
