what did you have to do about the oil squirters?
I'd have to look for the pistons but I know as of a few months ago they had a few still on the shelf. Since Nissan pulled the plug on the sponsored 370Zs JWT just has these as spares sitting around.
The pistons have a slightly shorter skirt and was told there is no clearancing of the block required (which makes since bc the vhr and hr blocks are the same).
I just picked the short block up from the machine shop and going through rod and main bearing clearance measurements as we speak.
Nissan gives you a chart to use for picking the bearing shell thickness which doesn't line up with standard engine building math. I thought i was smart and went by calculations instead of the chart.... Lesson learned is use the OEM cheat sheet because standard engine math put me 0.001" bigger oil clearance than spec limit.
