Mark Williams rearend?

[suntech]

Any of you guys familiar with the Mark Williams modular rearend? First plan was to put a Dana 60 under my 68 Pro Touring project, but they have one downside, and that is the weight!!
With a pro touring set up, roadhandling will be better with a lighter rearend, but the 8 3/4 will not hold up against the power in a hemi, so i will look for something more radical! ant thoughts about what to choose??

What's wrong with an 83/4....it's plenty strong for a pro touring application. They start to break with big power and big traction at the track. I would have no problem putting 800hp in front of an 83/4 with street tires.

suntech: I'm not at all familiar with the rear end you are asking about, but the aftermarket Dana 60's are within 10 pounds or so of an 8-3/4. Some are actually lighter.

My Strange D-60 is supposed to be only 10 or 12 pounds heavier than the stock 8-3/4 though I never weighed it, but you probably don't need to upgrade if you aren't using slicks.

Is it the S 60 you mean? Found that on the Strange website. That is a Dana 60 housing they have made themselves. Looks great, and it was what i was thinking of doing, just order a complete assembly from them, with 35 spline axles, and true track locker. They are also reasenably priced. But people tells me tha i must be nuts, to go through the task to mashine out all linkage arms ( 4 link/ watts link) in 7000 series aluminum, and hook it up to that bil ole heavy lump!!! Does anybody know the weight difference in the different assemblies? i would like it lightest possible ofcause, i mean, we put on alloy wheels to reduse the the weight below the springs, so it does make sence, and the Mark Williams http://www.markwilliams.com/detail.aspx?ID=1254 , looks awesome. Kinda pricy though, compared to Strange!!

my buddy has 1300hp in a dodge truck with a 8.75 rear end...     it hold up quite fine,.

This is good to know, I have been trying to decide to build the internals a stroker, but was caught up on the extra $ into a dana.  I have a 3.23 sure grip w/ 2500 stall, figured might as well stroke the 440 since I can upgrade things later, 
    but what about the 727, I was going to rebuild this stock before, with maybe 480 hp going through it, but with a stroker, will it handle upper five hundreds if the car doesn't see track?  well, maybe once      I know you sort of answered to this before, but now this rearend thing is new info, wonering if trans. maybe doesn't need a big $ uprade from a stock build?  thanks, Nate
oh ya, is it just ridiculous to try and use hp exhaust manifolds with a stroker big block and aluminum heads?  even if the K58 engle has the 112 degree lsa?
