For those of you running quicktimes.............

Lee---I was extremely glad to see you join this thread as I know that the stuff you work on has some similar concerns---
Since in a clutch coming apart, most of the stuff will leave the explosion on a tangent line, the lakewood with its larger size will have a better deflection angle to slow the parts down. Also since the QT is closer to shape of the clutch assy, it will funnel all the parts to a more concentrated area along the front edge and it will get there at a higher velocity, causing more strain on the existing holes for starter and clutch arm openings.
This design was created as a replacement for a bellhousing in a vehicle and I applaud the effort in doing this, whereas the Lakewood was designed as a Scattershield for multi disc clutches in dragsters and actually got a big boost when SFI banned the Llum Donovan units, even with the steel liners. The requirement for scattershields in the bodied cars equipped with starters was when Lakewood started putting the starter pocket on them , however they remained round, and closed with the front plates bolted with 25 (I think) bolts to the can.--this is where the QT comes up short---out of all there units, only a very few have all the fasteners, and of those that do, ground clearance will suffer.
I am going to take a bunch of pics today of a lakewood from one of my pro stocks and also a couple of block plates plus a 1/4 7075 alum mid plate like is used in real race cars, plus the back of a few blocks to show how race blocks vs oem blocks are

Lee--this wasn't all directed at you, sorry if it reads that way---see you thursday??If your coming maybe I can bring all the parts and you as a engineer can help with the proper terminolgy and photos
