Gregs finished flows are:
Intake:
.200” 147 cfm
.300” 219 cfm
.400” 267 cfm
.500” 301 cfm
.600” 330 cfm
.650” 337 cfm
Exhaust:
.200” 123 cfm
.300” 171 cfm
.400” 223 cfm

Not bad for a set of 5.3 heads huh?

Yeah those numbers are locked up.
I ran the car last night at the track and blew the driveshaft in half on the first launch.lol. A fellow LS1tech member showed up with his stocker so we swapped in a 1350 u-joint at the track, installed the DS and made a few passes. We ran some 10.6s with 1.48 60fts at 126.6 mph. I didn't get to do a good test on the lock up switch. We ran out of time.
The triple disc lock up clutches are extreme components in this converter and will not slip under a load. The tranny will slip first. I don't have any stats to compare the 2 outside of the lock-up features. You can't compare the lock-up clutches between the two. The efficiency should be very close though.
1.48 60fts at +2200 DA in a 3640# car is respectable IMO. I actually need a little more stall on the launch and I'll see high 1.3s if I can get her to stick.

I've got a 3.5" Dynotech MMC drive shaft being built as we speak. I should have known the stroker was on it's last leg.
Circle D wants to raise the stall a little more to see if the tires and suspension can handle it. 1.48 60 fts was great in the Texas heat was great, but a 1.39 would be sweet especially since we are a bit on the heavy side. Iguess we'll find out huh?
See ya at the track!
