I have a 1966 Thunderbird with a 428 and was thinking about puting it in a Mustang body. Do you know what years a 428 will fit into without problems? Are the motor mounts the same?

not without some major modification

The 428 will fit 67 and 68. The factory put in 390's in 67 and the 428 in 68 (both FE motors). The heads have a special exhaust manifold bolt pattern for the Mustang/Failane. T-Bird motor mounts would be different at the chassis.
The FE will not easily fit the 65-66 body unless you cut out or notch the shock towers and use aftermarket front suspension.
Good Luck.

It will in mine but I dont have shock towers.
If you do all the astro lube in the world wont help you.
Kay now im done acting like a punk.
The shock towers and cross member will be the problems on any FE motor.
If you have one all ready check the horsepower and either build a small block 5.0 with the same or more power or get a mustang 2 setup like I did.
If you can weld and do the work yourself the suspension kit would be the cheaper of the 2 imho.

no fit on 65-66......unless you modify shock towers and or install 67 style towers on early models...listen to Tarafied1.......he's right on

67-73 Mustangs like the FE engine, with factory support for 67-70.

Thanks!! Sounds like 67-73 will work. Which would be the best/easiest?

71-73 have the most room to work with
