Engine nicknames?
 

This is a weird question but has had me wondering for awhile.
All the older Harley Engines have names such as the knucklehead, panhead, shovelhead..etc. I was wondering about the nicknames of the newer engines from the Evolution to the present day engines.

I have heard people refer to the Evo as the "blockhead"...
What are the names of the newer engines if they have any?
What have you heard?

Twin-Cam = Twinkie.

I have a couple of Harley history books that call the Twin Cam a "Fathead". Never caught on apparently.

Hey Schumacher you sure your real name isnt Eric,cos you sure look like youve got some Viking blood in you?

Do those same books refer to the EVO as a "Blockhead"?
I wonder if some of those names were used internally at H-D.
EVO and Twinkie are common names for them. I've never heard a different term for the Revolution engine.

Evo & Twin-cam

around here they just call them Evo's and TC's / Twinkies.

I think American Iron magazine calls em Blockhead and Fathead. H-D never called them anything until recently. They were called E or F for Knuckleheads and Pans. Whatever alphabetical designator was how H-D called em. Knucklehead & Panhead were enthusiast names. Now H-D uses em.

Iron Heads.
