Thanks Tim. I have been covering this for a long time in fear of being laughed at.
Silver lining.
I need both engines. In these last years I have purchased 2 trucks. The 55 2nd and the 53. They both need engines. So. Manny, Moe, and Jack (actually Archie, Marty, and Zack) at Plano Machine Shop are 'chomping at the bit' to go pick-up/finish the other 235 down at the first guy's shop. They know him and are not suprised at my story. They are good guys and the machinist is a Model A (or T) guy. He is fun to talk to. They want to do the right thing and are methodical (professional).
I told them "when this one is done - go get the other." They smiled. Very cool.
Thanks again. This site is a wonderful relief and full of great people/information/ideas/inspiration.
