Hi all I was just wondering which one out of these two engines you think is better and why?

Facts and figures would be good but the most important thing is your personal oppinions.

thanks all

They are essentially the same engine. The 302 does have some very small advantages and the fact they are identical in physical size, the 302 makes a better choice, bigger capacity and all that.

Maybe for an all out race motor where you want to rev to moon the shorter stroke of the 289. But as said they are the same and can be stroked to 347 as well.Depending a on what model 302 or latter 5Lr HO efi block the 289 is stronger though older then it depends on carrosion etc... ...

289 motors are good reving motors comparing them to 302's and especial to 351's. As for the stroking 289's you can't go past 3.1" stroke because when ford changed over to the 302 they basiclly extended the cylinder bores to help increase piston stability. The 289's don't have this upgrade and you definetly don't want the piston moving too far out of the bore at BDC. This dosen't apply to the SVO blocks....
