Lmackattack Posted October 5, 2015 Share Posted October 5, 2015 The 350s needed more than 5 gears to keep them in the power band. I think minimum was a 7 speed.You could however have the pump set to a maxidyne 300 spec and it would be fine. 2 Quote Link to comment Share on other sites More sharing options...
