had a play with dropping it into second last night while at 60mph - its just the answer I was looking for...
felt un-natural to start with as it wouldnt have been something I would have tried with the stock L98 lol

I've been down the strip hundreds of times already and so far, my stock Dana 36 refuses to go. I've been cutting quite a few 60' times lower than 1.7 seconds and DEAD hooking, but no breakage yet. I'm still driving this car on the street on weekends with the big 4000 stall.

I keep hearing of Dana36's that seem to take the abuse of the drag strip - Was there any different models? Some stronger than another?
It would be nice to know! Maybe we should have a Poll?

I am going to go say you will see a big smile on your face with sticky tires. With my street tires 1st gear (the hardest accellerating one) is almost useless, as at anything under about 30 MPH, if I punch it the tires go up in smoke, and the car goes nowhere. With my drag radials punching it in 1st is like being launched from a cannon. 
A quality higher stall converter will help that third gear condition as it will allow the motor to be in that powerband all the time. But you have to hook that power up first.

High duration cams require high stalls. (higher then 2200). If your anywhere in the 230 range for cam durations a 2800 stall minimum to take advantage of the power. Higher gears is also needed. At least 3.45s . The difference will be night and day. You will sacrafice milage though. A 3200 stall from Vigilanti felt tighter and smoother then the 2400 stall that came with my new tranny. With a Vigilanti you wont be able to tell you have a high stall till you mash the pedal.

and Im seeing 1.7 60' times. I might be one of the lucky ones. If I had a D44 I would throw a bigger stall in there.

Must be! I don't have exact numbers, but I would guess I'm around 400 ftlbs to the wheels. I had 3.73s, 2800 stall, and MT et streets. Never took it to the track, never launched hard. Just a few downshifts and some WOT shifts.
Now, I have a dana 44.

Over the years I've learned that the flat torque curve of the LT engine makes it hard to feel and appreciate any power increases. An automatic makes it even harder. I kept modding and thinking, humm, didn't seem to do much, but the whole powerband keeps moving up, not just the peak. On a peaky engine its easy to feel how each mod affects the powerband. A good 9 inch TC will help.
