If you truly want to go "wicked fast" at the drag strip then you need
an automatic transmission. A manual is fun, but very difficult to get
really good 60 foot times with at the track. And if you're at all
serious about "wicked times" then you'll need a good high stall speed,
with a trans brake in an auto trans.
It's just not a simple task to get a manual trans to launch well at the
track, at least not without a well tuned suspension and an adjustable
clutch.

I'm debating between a tranny

In time I'll get everything ironed out, but for now simply looking for
what works and what doesn't.

Re: [Chevelle-list] overdrive thoughts
Are you reading GV's hype or have
you actually used one,Devin? The reason I ask is a few people that own
them say their gear splitter function doesn't quite work as slick as GV
says,,that their main benefit is reducing the final drive ratio.
If your road use only consists of
a 35 mile jaunt to the strip once in awhile,I think I would save the
money and leave the car alone.
Just my opinion,though.

The trick to the GV unit is that
1st over is almost identical to close ratio 2nd gear. This allows you
to hit first over when you would normall grab second, without having to
clutch or move the shifter. Then go to 2nd over at the nest shif, then
3rd over, never actually shifting into 4th, although the ratio in 3rd
over is almost 1:1.
While the 4.56s are deep for an
ordianry BB, mine's happiest between 4500-7500 rpm. If I went to the
TKO I could put 3.55s back in and still have the same total gear ratio
I currently do in first with the 2.20 geared Muncie. As it is, I'm
only going through the lights at about 6000, where I'd like to be
closer to 7000.

Re: [Chevelle-list] overdrive thoughts
4.56 cogs are a lot of gear of
a big block,unless you're running 1/8" mile. If you run a Gear Vendors
unit,the weak link is still the Muncie trans. Not sure how one would
allow a clutchless 1-2 shift,though. Herb is more familiar with the GV
od unit so maybe he will add his input.
A Tremec TKO-600 would be
strong enough but have heard they don't really like to be powershifted
at 6500+ rpm. The shifter position probably wouldn't be a problem and
very little tunnel work would be required,if any. Cost would be a
wash,too. You wouldn't need a 4.56 cog with their ratios,either.

To all- I'm debating
between 2 possibilities for an overdrive in my 64 and would like some
feedback and experiences. I'm running a 454 that is on the ragged edge
of street-ability, Muncie M21 and a 12 bolt with 4.56 gears. My
primary use is dragracing, but I drive to and from the strip, 35 miles
each way. I'm running nearly 4000 rpm on the freeway to do 65. My
thoughts are between a Tremec TKO 5 speed or a Gear Vendors overdrive.
The Gear Vendors unit has an advantage in that it allows full-throttle
upshifts, making the 1-2 shift clutchless, but leaving me with a trans
that is way underrated. I expect that someday I'll end up scattering
it. The Tremec is much stronger, but I've never seen one installed and
really don't want to move my shifter position, not to mention I don't
know how well they shift at speed. Anybody running either of these
options out there?
