Randy you are doing exactly what I do with my 68 Fastback really 100% the same thats awesome we live 8000 km away Iīm a "young" guy you are a racing legend and we have the same idea about our drag car.
Mine is a 68 as I said, now with a n/a 438 cui Aluminium Ford Racing Windsor build by ZSR Racing Engines it runs on normal german fuel from the gas station and makes 757 hp at the flywheel. First training runs were arround 10.2 now BUT on a unused airfield with no prep only some rubber in the afternoon on the track ;-)
My 68 is also stock body/chassis except the cage. And I have 2 sets of doors, trunk lid one in light one in original ;-)
I want to go from the powerglide to a 4 speed this winter, yes call me crazy but I love 4 speed so much also with drag racing.
Please post some pictures of your car here. I want to see it. I only have seen some racing pics long time ago.
