well sounds similar to my prob. my mate is building/freshening up a VG valient with a Hemi 6 cylinder (probably to similar to the one running you down). auto and heavy weight. im ####ting myself cause ill nail him off the lights but yeah he'll nail me top end, and i dont wont him running me down. i told dad about my situation and he said we will work something out! i only have to beat him to 100km/h. cause tradition lasts, we have to have the quickest car in grd 12!
