No question the D60 is stronger.... and looks super cool ( mean !) under there.
But I am looking to build a sleeper and a Dana is a dead giveaway. Thats why I went with W2s and a M1 Dual plane. Too keep it stock looking at a glance....
I might race it 2 or 3 times a year and would build a 4.30ish spool setup with a nodular housing for those occasions. I have swapped pumkins before racing many times and its not a big deal.
I once drove to Spokane to race with 2.9s and swapped 4.10s in front of my sisters house where I was staying ..... the guy accross the street had a few GTOs and couldnt believe I was swapping gears when he asked me what I was doing.... it took less than an hour... he was in awe ! Im sure he was picturing his 10 bolt process....lol
So if that 8 3/4 housing is stout enough I figured I might go that direction....
