IMHO, We drive these cars for fun. I don't think any of us expects them to be valued like an original.. well, not many of us. If you know everything about SBC and little or nothing about SBF leave it alone. The inverse is also true. It's your car. Make YOUR car. Of course if you decide to leave it with the SBC, you should get used to looking at the backside of lots of cars with Ford powerplants!
