pictured next is the large bore head gasket in place. This particular block had the coolant holes repaired, not an issue with the production run.
so far - so good
block was sonic tested and bores have plenty of meat with 4.350 bore. there was core shift, though and allpontiac is addressing that issue as well. Keep in mind this block is a prototype and all minor issues are being addressed. Of the 3 blocks being tested, all info is being compaired and addressed - pretty impressive - gotta love what these guys are doing to get a quality product out there.
