Ended up selling the car before I had a chance to finish it...due to rust issues with the body itself
I still have my motor sitting on a stand just haven't found a decent shell for the swap. When the time comes, I will be using as much of the newly developed Holley Blackheart parts as I can instead of trying to do a hodge podge of parts.
These are their newer exhaust manifolds for the swap, haven't seen anyone actually install them though.
