Yea, that's kinda the plan. It's already willed to my daughter. (because I sold her 71 GMC stepside big block that I built back in the day). Haha (I sold "her" truck).OK, with all that said, then if it were my car, I would do a serious cleanup and some detailing under the hood. If the plan is to rebuild the original engine in the future, I WOULD KEEP IT and open it up to a 383. Since you are in Texas, I'd also consider adding an aftermarket air cond unit. And I would keep it and drive it.
We bought our 70 conv 24yrs ago for a good price and today I could sell it for a VERY GOOD profit. But we bought it to have a Chevelle, NOT as an investment.
