Hi All, I have a 69 Mach 1 with a built 351W. I’m looking into putting a 427 into my Mach and was wondering if anyone here has done this and how simple or difficult was it? Thanks!

But like JTS mentioned, nothing from your current setup can be reused, including the trans and any related trans parts. Perogie Enterprises in New Jersey should have everything you will need to install an FE motor in a Mustang. When searching for parts I wouldn't mention it's a 427. That might drive up the prices. 428 and 390 parts should interchange, at least things like the accessory brackets, pulleys, and motor mount parts.
You can stroke your 351W to get 427 cubic inches. But I wouldn't. The bore to stroke ratio is completely different than that of a big block so it won't behave at all like a big block. Plus, stroked small block motors have shorter life spans simply because the long stroke causes the pistons to travel far in the cylinders.
