Marc,
No, no. No thread missed. My Mustang was done a while ago. So long that everything needs freshening now. It is an older picture. It's hooked to my Dad's 72 F250 that he bought new.
My first dedicated track car is the Wagon in my avatar. 67 Fairlane just like you have, only a Wagon. I have done the Calvert stuff, notched the towers, did the frame connectors (although not as cool as yours). Had Survival Motorsports do a 482, waited on a BBM block until I could not wait any longer and went with the block l had. Marine block. Had a C4 done with a good converter. I did do the Shelby drop figuring it could not hurt, and at the very least the tires won't be at a weird angle if the car starts hanging the hoops.
So, I have the fuel system, shifter and instrumentation and wiring to figure out. Want to get the car old school lettered, too. I wil be interested in your progress, so keep the updates coming when you can.
Mike
