Hi....I just read somewhere that the 1984 FXSB Shovelhead engines had Evo bottom ends, does anyone know if this is true?

 

its this way not the other - the first evos shared parts with the late shovel like the rods and the equal size flywheels / pinion shaft and for a very short while the sprocket shaft with the key way / oil pump and cam / pinion gearing but not the block that was still shovel before 82

 

Thanks for clearing that up John...
