i intend to visit the track now and then not just cruise.
seems to me running stronger joints are better than smaller ones.
i'm not as concerned about the 8 1/4 as its handled this motor for years.
and the trans has a billet drum and bolt in sprag.

my ? is the pinion spline count wich will enable me to order a yoke without first removing the old 1 to count or finding out after removal there isnt a 7290 or 1350 available. i have seen 27 and 29 spline .
