    Looking for anyones thoughts on two spd verses 3 spd in an automatic pro mod car? Do not hear of many fast cars running two speed trans unless its 1/8th mile, looking for more thoughts on 1/4 mile stuff. Thanks

    I know it's not a promod but we fitted a quick drive/2 speed b&j behind a bae screw motor for this season we ran our all time best this past weekend of 5.99@216 over the 1/4,we ran a clutch and 3 speed in the past with a roots blown hemi,we ran our best mph of 229 at the previous meeting,they will work if you get the correct gear ratios
