Ive been talking to injuneer on the subject and figured id ask some more ppl if they have had clearance issues or any other issues in terms of the torque arm on installing a gear vendor on a fbody.he said he had no issues at all but figured id open the topic up for discussion.
I have a th400 on my 94Z and the highway rpm with my 373 is just too high and i can almost watch my gas gauge plummet lol.

i know things i ll have to change for sure is a shorted driveshaft and prolly just do true duals dumped before the axle instead of any y pipe.
