my 60 foots are like 1.6- 1.9. It really isnt all that stock either, due to the tranny issues i am having i am losing a ton. i have heads cam swap, headers,longtubes,150 spray, 4:10 gear, nitto drag radials. dynoed close to 420. i have a small cam though. I will be changing out motors this winter. time out / your running that with stock heads no porting nothing? what mods you have done?
