You may want to shift the fuel tank and battery forward to help improve static trim. To get a feel of the new engine weight, calculate the difference, add to the spashwell. Remember to include your full model in your post 1986 XX Super Sport Limited 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT
