I have a numbers matching 1970 Swinger 340/727 with factory A/C. I found the build sheet, all legible, undre the back seat. I rebuilt the ALL original motor, but wrapped it in plastic and put it in the corner. I'm building a TF head 408 for her, because I want to run her hard once in a while, including the occasional 1/8th mile at the local strip in the summer. I'm keeping all the body stock, and not doing anything that can't be undone to restore it and run it across the block at Mecum. I'm not being an a**, but I'd like your opinion on my plan if you were in my shoes. Restore and baby it, or go my route with a "disposable" engine and have some fun on the streets? I respect your opinion, I'm 63 and questioning my plan. All polite opinions are invited. Paul.
