Who wins the battle to build an A833?

I would advise using a hemi 18 spline transmission. I ran a 23 spline A833 for less than a season with 14x32 slicks and the green clutch launching and shifting at 7000 with a 340 and the input shaft had taken a permanent twist in the spline just aft of the clutch disc. I don't know how much longer it would have lasted.
