strokin the 400 tips needed
There have been a lot of posts on the subject. You may want to try a keyword search using "stroker".
I think the stroker I talked about, https://www.ford-trucks.com/dcforum/DCForumID12/1068.html
is the most inexpensive.
The only problem is getting the compression down to a streetable ratio.
If I'm reading the info from this site correctly,

custom thickness head gaskets can be ordered.

OK here's three ways to make a good street 400.
1. The 351C piston on stock 400 rods bushed pins..with the right C.H. you can have a High Compression 400.
2. 240 6 cyl. rod is 6.79 off grind crank to 4.18 add KB235 pistons, and doing your own valve reliefs. And decking the block to get your Compression you want.
3. 300 rods and stock height 351m pistons? The pistons should go right on the rods and the deck clearance ought to be pretty close. All you have to do is narrow the rod big ends. offset grind the crank to 4.18".
