Correct, it's vvti, with Kelford street cams. The cam specs are further up the thread. Since I had the engine apart, and my goal is to pass California smog inspection if possible, I serviced the air injection system and replaced the pump--using the vastly cheaper GM pump noted by several users on this forum. I just installed the engine with the stock exhaust, which I'll switch out when the smog verdict becomes clear. The only thing I didn't reinstall were the heat shields on the manifolds, because they make it a lot harder to get the manifolds on and off. May be a problem on inspection, we'll see. But I'm ~hoping~ I'll be able to smog it, then take it to the tuners with the new exhaust. If it won't smog, I'll move on to plan B.
