No racing for us in '23 after waiting for engine parts and a house move. We bought a property but still haven't moved, it needed more work than we first thought. We did get all the engine parts we needed which included some new 600-13 X heads for the 655 engine. The 580 motor was rebuilt / refreshed after nipping a ring land in late '22. This occurred after the head warped, allowing #3 cylinder to pull in oil via a head stud. It still ran a pb of 9.51 prior to that. We had to skim the heads 0.010 which has now upped the C/R from 12.5:1 to almost 12.9:1, the heads are 572 -13 and this must be the 4th time they have been skimmed.
2023 plan is to do a couple of meetings with the 580 to make sure all is well, see how it performs and then fit the 655 for later in the season to try for 8's N/A with a 4000lb race weight.
