Can you bore a 351 ford stock supercharged motor to a 454?

Ok, i have a 2002 Ford 351 Motor. It came out of a Ford SVT Lightning.. And a friend told me i might be able to have it bored out to a 454? is it possible? and can i keep the supercharger on the motor?

Your answer is no. But, You can stroke it to 408 cubic inches with a 408 stroker kit. But you don't have a windsor you have a 5.4 modular engine which can also be stroked, but leaving the stock supercharger on a stroked mod engine would kill power. Good Luck and look up johnny lightning performance to get all your lightning info and parts.

No! If the 351 could be bored out that large the cylinder walls would be so very thin that the pressure from the blower would shatter them. No in all reality it can not be done. In fact a 390 can not be bored out that large since an over bore of just 60 thousandths would leave the walls to thin. You would have to start with the rare 427 block and then modify that. In my stock car i once had a 390 with a 60 over bore, and the first time out I cracked the cylinder walls in two cylinders.
