We went to "exercise" the Backdraft and its 427 small block. I had been thinking about 3.73's vs current 3.46 rear axle. 3.46 is fine so I guess side pipes get the "tennis ball" test for my winter project.
With 8 quart
oil pan and
oil cooler, warming up takes a while. Next time we're using GoPro for video.
Gotta go,
Russell
