Just now stumbled upon this website that details the construction and re-engineering of the new-build Fw-190A-8's by Goshawk. Some neat engineering involved- especially the new oil coolers and air intake trunking. Looks like the Ash-82T engines have the same magnetos as fitted to USN F4U/F7F/F8F R-2800's
