I might get a set of pistons too, this would complete my car. I dont have a crank, but i am very interested in the one you have. I would want to lighten it too. The pistons are in your car right? If so could you tell me how they worked out? My brother had a small problem with his where they had to trim a thousandth of an inch off the top of it becuase it wasnt clearing. I would like to get J&E pistons, probably same specs as yours. It woudl also let me wind out higher after the new intake manifold.
Its good to find someone who is going the same way too, I felt very alone and no one to compare products and ideas with.
Good luck!
