C4 Dana 44 durability ?

[Texas Hotrod]

Hey everyone.
I've been working on a 68 RS/SS for a while and have a C4 IRS swapped in.
Went all-out on the thing for a long time (got burned out) and mothballed the car to get several old bike projects finished up.

Anyway..........
The last couple months have been really productive but strayed from originals plans.
The sb 400/700R4 was ditched and a 461/4L80 is in assembly.

My gut feeling is to remove the IRS and swap in a 9" (I have the unit w/3.50 posi). Mainly needing a set of Strange axles and I'd have a worry-free rear end.

Yet the IRS is set up in the car and is the ultimate pedestrian-viewing upgrade.
All I'd need is a 44 pumkin and strengthened shafts.
I'd really like to keep the IRS, but I fear blowing a yoke or u-joint.

So my question(s)........
Will a 44 center bolt into the 36 batwing?
and is the 44 capable of 800/900/1K HP?

Thanks.
