Stock Mopar mini starter and hundreds of hundreds of passes behind both a big block running 8.60's-8.90's and a small block running 10.0's-10.20's with a stock 1.76 gear-set. I broke a set of stock 1.82 gears after 125 passes in a 2800 pound big block car. Don't bother running that gear as they are on the smaller carrier.
