72 duster 360 NA to 390 Turbo

We got new tires! MT ET streets 275/60/15. No more spinning at 50mph! Plan is to go to Rockingham Mopar show Saturday and get some 1/4 mile full throttle runs. Dead hooks on the street now but the trans isn’t liking the 1/2 shift. Transmisson was fixed by a friend of mine in 98 and has live thru a 318,360,360 with turbo and now 390 with turbo. I will post results good and bad.
