    My a/c manifold hose developed a leak at the rear of the block where the aluminum tubing actually started tearing way from the manifold assembly. Got that replaced. Installed my oil cooler adapter and lines. Cleaned up my 0411 swap wiring. Played with the calibration a fair amount as well. Also got a line on a L31 Marine intake and dug out my set of now discountinued Doug Thorley Express van headers. I should be up around 425-450 ft/lbs of torque and 375 HP when I am done. I also brake stall tested the B82 converter behind my lightly cammed L31 5.7 and found it stalled just under 2,150 rpm with the drivetrain fully heat soaked and it was difficult to keep the right rear tire from spinning. With cooler IATs it flash stalls 2,300-2,400 rpm. I have a GM 9.5" ring gear corporate 14 bolt to fix the one wheel peel. As it is its not running too badly, runs 0-60 in 8 seconds, about 1 second slower than a 2000 C1500 4.8/4L60E/3.42 geared RCSB truck with a CAI, Headers, and Catless exhaust that I tuned the other day. When the weather cools off and the other parts find their way on, it should run well into the 7s 0-60 range, maybe even touch a high 6 second 0-60.
