You are just as bad as I am, can't leave well enough alone ! LMAO

Headquarters does sell CP Pistons - 3.938 bore with a 7cc dome for $391.40.

With HQ heads this is a 10.5:1 static compression, would be marginally different depending if your heads have been milled, chamber volume, etc.

 

I got my 98" CP's from Randy (KOC) http://www.kingofcubes.com/ He cut 10cc domes down to 6cc and bored the cylinders to match. I couldn't be happier.

one name in pistons "Wiseco"...http://www.wiseco.com/Catalogs/VTwin/TwinCam8896.pdf

take the CC's listed and divide by 16.3870641 to obtain C.I.

Or , take C.I. and multiply by 16.3870641 to obtain CC's.

 

I was just playing with the calculators again, and these 97" kits look like they will fit my needs better then the 98" kits will. I'm looking to raise my compression just a bit to better fit my cams needs, I'm set on paper at 10-1......but when I enlarged the relief pockets in the pistons I'm sure that dropped it down a bit. So by going to 97" with pistons that I won't have to work on, that should put the compression around 10.25-1 that the Woods cams want.

S&S has a 97" drop on kit with new cylinders for $725, and Axtell has a 97" drop on kit with boring for $460. I'll be doing this over the winter, so downtime is not a big deal to me as I'll have 4+ months to work with.
