well warmonger is running 9psi on stock pistons + rods, on his 3L...I think the last time I talked to him on the phone, when he had his old 3L (my new one!) he said on 8psi with the stock pistons+rings his dipstick tube would pop out like 3 inches!...10psi may be a little on edge, the EGT would prolly be pretty high at that level of boost and with the stock rings I think you would have a little blow-by. I would suggest at the least when you rebuild it put in some good pistons+rings and some clevite 77 rod bearings. The you could run 10psi safely.
