WELLLLL. After plenty discussion with others and time for reflection. I think the route im going to leave the Poncho motor in. My good friend said it right that now days you almost expect to see a LS motor in these classics at car shows. When you walk up and see a real Poncho motor you actually get taken back.
My current project is a 4l60E to be built and Swap. Then going to do EFI, then later down the road take the motor out to stroke & bore.
So it will still have the heart and the look of factory just with a flare of modern.
