I'm a 63 yr old gear head with a 1964 Ford F100. Retired, so I play with my toys full time, until the other of life's projects prevent me from doing such. FAA A&P license in 1976. Personally built three ultralight aircraft, 1 rag and tube, and two composites. Here to learn as much as I can on F100's with Y blocks. While I'm happy to help in any way possible, I'm the student here with little to no Y block experience. Thanks in advance and hope to meet each and everyone of you online! "J.R."
