I found the pistons I've been looking for on ebay for a great price, paid, then noticed something the next day in paypal.

I wasn't sure what to expect, but today FedEx stopped by with a USPS box that was all covered in tan tape. I wonder what he's doing, since they're K20A itr slugs shipped in a CP Pistons "SC7147" box:
They actually have thicker ringlands than CP pistons:
Anyways, I just need rings then bore my f22 block to 86mm to match. With the A6 head it will be 11.8:1, and the H22 head it will be 11.1:1 CR. It will also be a hair larger displacement than an 87.5mm H22. I've been thinking about getting Delta to regrind the cam(s) once I get it all running. Of course it will be using my 370cc injectors, maybe at 4bar pressure if they need it.
I found a build with an F23 block, A6 head, k20 type-s pistons (10.8:1cr), and 272 cam do 194whp on a Mustang dyno with DSM 450's.
