i blew a 4.6l in a 98 f150, 4x4 auto transmission, tried to replace it with a 97 f150, which came with a manual transmission, and the mechanic said the new motor will not fit due to the crank, and the flywheel, is this possible, or can they not be retrofitted? they are both windsor motors, i thought any ford motor can replace a ford motor
the engine should be able to fit. that should just be as easy as dropping it in and swapping out the transmissions and any additional hardware that may be required.
Soon after I got my '98 F150 4X4 automatic w/4.6 L, the experts schooled me on how to tell if the motor is a Windsor or a Romeo. Apparently chains like AutoZone are cued to ask for VIN to resolve this Q, even to replace the serpentine belt!

Since h20fella posted "blew a 4.6l in a 98 f150, 4x4 auto transmission" I'd presume he has the same odds of having either Windsor or Romeo. However all the 4.6L '97 & '98 motors should physically "fit". If "they are both windsor motors" I'd expect most of the connectors to also "fit".
Counting flywheel bolts can be kind of a hard way to make the distinction between Romeo & Windsor. Many can tell instantly just by looking at the cam covers, which have different bolt patterns. For my work they also had different harmonic balancers.

Looking at VIN numbers can be much easier. If there's a W at a certain position in the VIN it means a Romeo motor oddly enough. Sorry I forget which position & have 2 W's in my VIN.
