Fuel requirements
I've got less than half a dozen n2o runs.. so it's not like that what it gets a steady diet of, even though it is built as a nitrous motor.
The rear end, though original to the car has been rebuilt. I used the original ring&pinion, posi-unit, housing, rear cover and 17 spline BBlock yokes when I went through it about 4 years ago. Went with a poor mans cryo and packed it in Dry Ice! Old school 70's...no money back then!...but we had Dry Ice.
I never thought it would last this long...but it has, so I thought mmm... wonder how long it will go before it grenades? I have all new 1480 joint/halfshafts and 12 bolt inners for a new build, but the 3.08's still working...go figure.
OH and I have to remind myself to STAY OFF THE TRANS BRAKE!

700 hp to a stock diff? How about the aluminum (ie; '81 w/ an automatic and 3:08 gears)? I've heard that the aluminum can handle up to about 400hp and then it's a gamble after that. Some input from experienced guys, please. Thanks in advance... And: is that 400hp at the crank or at the back wheels? Thanks again.
No racing, just spirited street driving.

Union 76 92 octane for 10.s and I just add 5 gals of 100 Sunoco unleaded for 9 sec. all motor runs. Nitrous that gets the good stuff 115

Overnight, remove it, let it sit all day at room temp, repeat 3 to 5 cycles... but this alone will not make it bullet proof! Much more to it. There are no short cuts to a properly built drive train. It's all time, and money spent.
The sound's the parts make is quite facinating...crink..crink..crink...
Has worked best on factory axles. Just the tip of the iceberg, so to speak
