<p>I'm running a DWR1 cam in my BJ8; about 250 miles so far. It
pulls smooth--even with a 3.54 rearend--from idle up to 4K RPM,
but seems to run out of breath much above 4,500 (not that I go
there often anyway). One thing that I noticed, and didn't expect,
is that when I decelerate in gear it seems to 'come off the cam'
at about 2,500RPM or so; my Mustang GT does this quite noticeably
at about 1,800RPM, but it has variable cam timing.</p>
<p>My engine builder commented on the light ring loading from my
85mm DWR pistons; that, and their lighter weight and 3-ring design
I believe reduce internal friction quite a bit.</p>
<p>As (bad) luck would have it, I cracked my pan and had to pull it
for repair, so got a couple shots of the cam and pistons in situ.<br>

<p class="MsoNormal"><span style="font-family:"Trebuchet

their cams other than the DWR1 require releaving the
pistons. My engine was just finished with a DWR1 cam with
his bucket followers and lifters, and I’ve had a DWR high
capacity oil pump for years. I also had DWR 85mm pistons
installed. Unfortunately it is not yet back in the car so I
can’t give you any driving impressions. You can talk to
Dave Nock, though; he runs a DWR1 cam, as I recall.<o:p></o:p></span></p>

<p class="MsoNormal">A few weeks back I mentioned to the list
that I’m considering using a Welch DWR8 cam. Based on
responses and more research I think I will go with the DWR1
with the bucket followers and longer pushrods. I also plan
to use the high capacity pump on my mostly stock engine. <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I was considering using the roller
rockers, but am not sure if that’s going to make any
significant improvement. I know it will buy a couple of
ponies due to less friction, but is there any other
significant advantage on a basically stock engine. Would I
be wasting my money on something fancy that really has
modest benefit? The DWR1 cam provides 0.252” cam lift.
According to Welch, the valve lift with standard rockers
would be 0.358”, and would not need pockets machined into
the block. Based on the 1.65:1 ratio of the roller rockers,
the valve lift will be 0.416”. I believe that will require
pockets in the block.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Does anyone have opinions on this
combination? The roller rocker assembly is over $1200 not
including getting into the US from the UK. Is there a better
place in the engine to spend those dollars? <o:p></o:p></p>
