first of all' I'd like to say welcome to ECS. the skill level and the commitment to your trade is obvious, and I salute the effort. and, I know from which I speak. I must tell you that although the cars(and trucks) that I do are usully only referred to as a "restoration" by the owner. I'm a body guy. I just clean 'em up and paint "em. having said this, I also know what the difference between the so called "restoration" and the "reference restoration". the term "survivor" means just that. if you find an untouched survior in a barn/shed/backyard, if it dont run, and you have to build motor or trans or rear or anything else, it is not a survivor. now i do agree that the #'s matching thing is very good to have, and if you can use the block, case, whatever, then you are at best a reference resto. we've all seen that roadrunner at the car show as a survivor. and there are some out there. i'm pretty sure that i personally have seen one. but his dad bought it new and the service records were all there to back up everything. very very nice. the car was as beautiful but it really needed fixed back. but you have to question if a restored 69 383 auto runner is worth more one way or the other. the sentimental value is always the line in the sand between the money spent or not. now my personal opinion. although the car has a chance to be a survivor, reference or resto only once chances are good, for me, that i will recommend a resto over all else because, it looks new, it runs new, it drives new, and the owner gets a ride he can be proud of for half the money. again welcome and post on. i've seen the a body somewhere before and it is a beaut. i own a couple and i like 'em.
