DYTCH 10.5:1 3.00" Bore +.040

These pistons are in nice condition.  They take 2ea compression rings and +.007 to +.008 clearance.  I'd like to try them sometime.  The tallest domes I've ever seen on an Ironhead piston !  I guess you must fly-cut clearance for the big intake valves?  Someone knurled these for oil . . .

I'll have to measure one and see if they're 3.040?  or 3.035ish?  Did he figure the clearance into the piston?
How did Dytch do it?  Doc Dytch that is . . .

I've got quite the exotic piston collection for early ironheads.  Anything I see at the swap meets for 3.00" bore I usually buy it, or regret it later.  I sit and dig through my collection and just look at them.  Probably never use them - they're just different attempts at performance.  I need a set of those Aries pistons(I think) that have the 3 teflon lookin' buttons built into the skirts.  Don't have those yet.  The MC pistons, Dytch, Axtell, S&S short stroker pistons . . . Some people collect spoons from different states - I collect pistons.
