Ok, you have a 1976 Corvette Stingray, you already invested a lot of money and time into a new interior. The motor runs but smokes and obviously is in need of a rebuild. Now...would you keep the original numbers matching engine and have it rebuilt with performance upgrades or...say "screw it" there's no real value keeping the numbers original and buy a performance crate engine? This is my bff's car and neither one of us can decide so we are asking opinions here, especially since we have several "vette" people here.
