That's one reason we love them so much! Right guys?
Simple swap, but like Darrel mentioned, you need the flywheel if you go with the 428 crank. It's cheaper to track one down if your boss doesn't have one, than to totally rebalance the entire rotating assembly.
Check your cylinders for taper, and bore accordingly, if you intend to be able to rebuild and bore again at a later date. If you do bore, new pistons are in order, and you'll need new pins, which means fitting them to the rods. If all you get is the 428 crank, and not the rods that were attached to it, you'll need to have your rods resized. (IF you go with the 428 crank, that is!)
Try to get a 390 with C6AE or earlier head castings. Casting # is between the middle 2 spark plugs. In case you don't know, the C is for `60's, the 6 is for the year in the decade, in other words 1966. C5AE would in turn be `65.
C6AE-R are good heads to have, and need little work to flow like CJ heads. Expense is always a consideration, but even stock, they'll flow better than any non-CJ head from `66 on. Don't be too obvious, but try to be snoopy a little if you can ;) and go for the older heads! Unless of course you happen to find some C8OE-N's, (CJ heads) and he doesn't know what they are... (fat chance!)
On the flip side, ask if you can remove the center freeze plugs, and look for "428" cast inside the water jacket. This is a good indicator of possibly a stronger/thicker wall casting, which can take more stress, and consequently a larger overbore.
If oil pans are off, or he'll let you take them off, look for the webbings on the skirt of the block, directly to the edges of the mains. the more ridges sticking up in those webs, the better.
I think my `66 T-bird 390 has standard webbing.
Someone correct me if I'm wrong, please! I'ld love to find out I got a tough block!
Here's a not so good pic, but it shows you where to look.

Right where the main attaches there is a ridge running up towards the top of the block at a 45 degree angle.
Cams are a consideration, but I'll let someone else help you with that. If noone offers info about them, post again specifically about your requirements.
Also post casting #'s of what you get. Heads, block, etc. |
