I agree with what Dan just said. JB, I would keep your 69 Sport Coupe all original, but this is coming from a guy who likes his 69's all original, exactly the way they were "born". It really doesn't matter to me if it is a Sport Coupe, RS, SS, SS/RS, Z28, COPO, or Yenko, I would keep the car the original color.
I remember a few weeks ago there was an Olympic Gold 69 Sport Coupe on Ebay. Even though it didn't have the "sougt-after" options like I mentioned above, it was great to see that color. It too was a survivor, numbers matching car. All 3 of my 69's are painted the original colors, Garnet Red, Daytona Yellow, and Dover White.
In regards to you sliding in a big block, well, I wouldn't go that route. I would keep the original drivetrain intact. I assume your 69 is a numbers matching car, since you mentioned that it is a surivor. So, with that in mind, I would go shopping for an ex-drag car or another 69 that isn't a matching #'s car, and use that for the BBC engine.
You mentioned you have the POP, so that is even more of a reason to keep it in stock/original condition.
Have any pictures to share?
