Thats what I was thinking. The balancer ring has quite a wobble as well. How likely is it the balancer ring could have spun? This thing has a ton of mid-range and top end, considering Im still running the small stock manifolds and exhaust for the time being. If I bring the stall up and hit it from a stop, it takes off like a 2bbl 318 until it hits around 2000rpm. Granted, I still have yet to adjust the air door and such, but the low idle in gear is whats puzzling. And forget turning the A/C on. Gotta "2 foot" it at idle to do that.
