I have no idea. I would be willing to bet around 12k. The guy I bought my B4C camaro from did a complete rebuild on his motor and installed a cam 9k miles before I bought it so I'm willing to bet he did the stall at the same time. Either way he had it tightened up by TCI after the cam swap so he could run N2O. I didn't put 3k on the car before I totaled it. I'll be selling the cam, springs, and pushrods out of this motor soon as well. It's a Vinci 216/224 .551/.551 115 and would be excellent in either a cam only 4.8/5.3 or a boosted app.
