I wouldn't mind picking up another pair of 4V quench heads. I have
two or three pair of open chamber, but only one pair of closed
chamber. Not that I'm greedy or anything. <br>
<br>
I wouldn't mind a pair of Aussie 2V heads with quench chamber, but I
don't think they'd be the best for racing, as I believe you are
pointing out and Chuck has validated since he's moved on as well.<br>

use Aussie heads that only produce 375 to 400 Hp in street

someone has thrown away or 302B and/or any similar alum
heads that make so much more Hp (475-525 at the REAR

the answer is, "because I don't have cool 302B alum heads
like you dawg"....or its, "the Aussie heads are just
better"...then I gotta say since I am IN Australia now and I
am hearing from the boys down under who want to seriously go
fast that they all want quench or closed chamber heads. They
will pay YOU to take their Aussie heads!!! Yea even in

someone is gonna make a NEW Cleveland block to replace my 10

think thats gonna happen. I suspect in September when I come

it will be driving that same stock Pantera averaging

Re: [TPR] Piston Ring Rotation.<br>
</font> </div>
<br>
Dear Asa,<br>
<br>
<br>
The first and second engines I built were done
with the standard<br>
ring positioning protocol. I then learned the truth: the
rings *move*<br>
during engine operation. They do not remain permanently in
place. The<br>
first two engines were with Aussie heads and made 401 and
385 hp.<br>
<br>
The next two engines were built with 4v heads
and absolute<br>
carefree disregard for the prime ring directive. Dyno
testing showed 440<br>
and 485 hp.<br>
<br>
I am about to begin the next engine and I will
continue with my<br>
laissez-faire piston ring assembly. It doesn't seem to hurt
engine<br>
performance.....!<br>
<br>
<br>
Scientifically yours, Chuck Engles<br>
<br>

Subject: [TPR] Piston Ring Rotation.<br>
<br>
Most of us are aware of the proper ring positioning when
assembly an engine:<br>
<a class="moz-txt-link-freetext" href="http://www.351c.info/gallery2/d/218-1/ringspacing.jpg">http://www.351c.info/gallery2/d/218-1/ringspacing.jpg</a><br>
The two compression rings should be spaced about 30* (or
about one inch)<br>
from the front centerline of the piston, one on either
side. The oil ring<br>
segments are the same on the opposite side of the piston
toward the rear.<br>
The illustration above shows this quite well.<br>
<br>
But do the rings rotate after assembly?<br>
<br>
A few years ago at the POCA Fun Rally, Jack had an expert
who was familiar<br>
with pistons. He said indeed the rings do rotate, so in the
end it doesn't<br>
really matter where you index them to start with... <br>
they're going to move.<br>
<br>
Today I recorded the ring locations on my forensics engine.
I had been<br>
careful not to turn the rings on the pistons when I removed
the pistons/rods<br>
from the engine previously. Because I can't insure they
didn't move at all,<br>
the relationships below are rounded. Here are the results.
My "timing" is<br>
from the -front- of the engine, moving clockwise. The
piston position at 12<br>
o'clock is the part facing front, the position at 6 o-clock
is at the rear.<br>
<br>
The first compression ring is at the top, the second on the
bottom.<br>
<br>
Piston 1st Comp 2nd Comp Oil/Oil<br>
#1 8 o-clock 4 o-clock 4/2<br>
#2 10 11 12/3<br>
#3 10 2 10/1 (probably the only
one closest <br>
to installed)<br>
#4 8 8 8/8 (All ring gaps were
lined up)<br>
<br>
#5 9 2 5/5<br>
#6 12 9 5/5<br>
#7 5 4 6/5<br>
#8 9 3 3/7<br>
<br>
As you can see, they are all over the place. I'll work up a
good<br>
illustration and post it later.<br>
<br>
Does this mean I won't index them the next time I assemble
and engine? <br>
Actually, I'll most likely still index them when assembling,
only because<br>
I'm anal about those things and I do believe spacing them
does assist with<br>
initial break in. If they are spaced the same, I look at
that as an easy<br>
path for compression gasses to get past. In other words,
gases might get<br>
past the lower tension oil ring segments and past the gap in
the bottom<br>
compression ring but then they'll have to travel around the
edge a while<br>
before they meet up with the gap in the upper ring. In the
end, it may not<br>
really matter.<br>
