Does anyone make a ring compressor with a tapered overlap and lever to close it over the rings?

I should have said that it has a slit, not that it is sliced.

I have two of these fixed size compressors, 4" and 4.030 but had to get
another one for my new 4.040 pistons. This time I bought an adjustable
compressor. It looks just like the other ones but it is sliced and has
a big hose clamp around it to set the size. I haven't tested it yet but
I hope it will work just as well as the other ones.

Hi Guys,
I am slowly putting together a 427FE engine for my Cobra. I'm
taking
my time because the 428 that's currently in the Cobra is running
great.
At any rate, my ring compressor was giving me fits. I have a
fairly
nice, old school, ring compressor that consists of several bands
and a
pair of special pliers that compress the bands. The pliers have a
catch. You squeeze it, pop the piston in place, and then release
the
catch. Pretty simple. Only it doesn't actually work that well.
So, I bought one of those tapered ring compressors. Holy crap this
is
easy. The piston slides in so smoothly, you don't even have to tap
it
with a piece of wood (bottom of a hammer). You can just push the
piston in the hole.
Never, ever use any other tool to install pistons. You have to buy
one
for each bore size, but how many bore sizes do we really use
anyway?
I'm also using really thin, standard tension rings. If I recall
correctly, they're only 1mm. I'll check tomorrow.
Btw, it's actually going to be a 482. I had to buy a crankshaft,
so I
bought new. It's cheaper to buy a stroker crank than it is to buy
an
original stroke. An original stroke crank is also special order.
Plus, the CR math works out that a flat top gives me 10-1
compression
as a 482. If I stayed with a 427, I would have to use pop-ups.
I'm still working on the Pantera. I just thought you'd appreciate
this
public service announcement. Jack - you should do an article on
these.
Will.
