Now that's what I'm talking about! Nice.
I have a set of 34's for a VW that I was going to use...not as pretty as those.
For all you flat head guys an FYI... The pistons used in oppy's and singles cylinders are exactly the same size as stock air cooled VW's
I'll try and post a pic.
Sorry pix won't load... 3 3/8" = 85.5mm
Pic was of both pistons.
