Left Handed Skyhook? - Orig Owner Story and Option

[Casey Marks]

This is a trait of 400's known as "blow shift". Basically, it is a fail-safe from the engine grenading itself. It is not an option, but a safety mechanism for the engine and trans. In fact, it can be seen in 700-4R's too. I was driving a buddy's 427 4x4 truck with a 700 in it, and just put it to the mat until the trans upshifted. Blow-shift is the "trans guy" term. Still cool tho ......

And if you stay in it, will do the same from 2nd to 3rd.

Some bracket racers never shift on there own, letting the trans do it for them, more consistant. But IMO, really takes the fun out of it. My theory is (not Rob's), shift when the beast quits pulling. Rob says that is what I tach is for.

Left handed sky-hook..sounds like something from boy scout camp....we used to send guys out for a left handed smoke shifter or my favorite, a "100ft of shoreline"

My understanding is 1970 was the first year for that in the Turbo 400's.

It was and for ALL GM vehicles w/TH400,not just Chevy,regardless of their Horse Power.It also did help keep service replacements ("H" units) at bay.
I really like it behind the L-78.

I think Rick you and Charley may have just saved a pile of 68/69 engines with TH400. Bad images in my mind. Ok they said 6300 lets try 6500 maybe 7000. Wow what a bang. Where is all the smoke and oil coming from.
For what it is worth I could never get mine to do it between 2nd and third probally the just the driver.
