Would you say you have obsessed on carb tuning (and ignition) and have both set up ideally? Got details of all that tuning you’ve done? Aside from that, (and not knowing rear gear ratio) I’d lose the converter for a quality 3500 tight such as from Turbo Action. That’s my knee jerk response :)
This makes sense because the one good burn out that I did do once the revs got up I could have went down the length of the guys driveway...Long driveway
