My toploader and rear end were built by Tom of Tom's Differentials (supposedly
where Shirley Muldowney got her rear ends built back in the day).
He said I could take it to red line, side step the clutch and at least from
1st to 2nd and 3rd to 4th I could leave my foot on the floor and just yank on
the shifter. Of course he didn't mention drive shaft or engine.
Have I ever tried it?
No.
Will I ever try it?
Highly unlikely.
FWIW

Not into it myself. Considering how difficult and time consuming it
is to replace a clutch or transmission on most vehicles today I would not do
it. I also do not want a flywheel or clutch ripping past my foot or any
other body part if they happen to fail.
I consider spinning tires and sliding sideways, the slow way to go
forward. I'm just not into drifting. You need a tire sponsor when you burn
up a set of tires every 10 miles.
Drag racers have clutch packs that are designed for full power
slipping. They also have all the safety equipment and parts to contain any
shrapnel and usually a budget to handle those situations.
Last time I side stepped the clutch was in a 71 Datsun 510 - thought
I was going to have to rebuild the master and slave cylinders for the
clutch. I'm not sure what happened but I did not have a clutch pedal for
about 5 minutes; it did finally come back and seemed fine. I won't do that
again.

Ok, I realize that there are differences of opinions, and they are not all
correct - but the holders usually believe their opinion is right. My dad
brought me up saying that power shifts were not good, a quick way to burn
out a clutch, and not the fastest way to accelerate. He said it was better
to match speeds, and not to put full power down before the clutch was
engaged. By "power shift" I mean an upshift with the clutch in, where after
you've pushed the lever into the next gear, you floor it, then drop the
clutch. I've been to countless car races and I can't say I've ever heard a
racer do that. I've never done it.
So my sister was over this last weekend with her husband and son. The son
was showing off his new Ford SUV that he swapped out the automatic and
dropped in a manual. It was some cool work, and he should be proud.
However, when he took my son for a drive, he did full power shifts -
bragging about getting rubber even in 3rd gear. When they came back, he
showed my son some You Tube videos of guys doing the same. My
brother-in-law who has some amateur drag racing in his past, just chuckled
and didn't suggest anything was wrong with it.
What do people think about this?
