Hi, Gary - good hearing from you!
Right now, Keith is investigating. I've sent him photos of the engine, along with a list of head castings utilized on the A-Series, and a list of modifications we made to the head - The head seems to be where the focus of the investigation is.
They haven't asked me any questions yet, but they've got my number. It's my hope that the thoroughness of the documentation we've provided under public scrutiny here in this build diary helps our case. The world has seen every success and failure we've put across - we're not hiding anything.
I'm aware you've had a bit of a runaround regarding your head as well. Combined with this change-up in the GT category rules, you, me and Tom Donney aren't sure which category to put on the entry sheet!
I'm still on the mend from chemotherapy and radiation last winter, was hoping for Speedweek, but banking on World of Speed.
BE SAFE, and the best of luck to you and Caitlin!
