I'm running that cam on my 64. It is very responsive at the low end
compared to some other cams that feed in at higher rpm. Had pockets
in block, DW bucket followers and pushrods. But I also have light
modern pistons, lightened flywheel, DW headers and a DW fast road AL
head and roller rockers, so your experience may differ. Attached
pic of block with pockets.<br>

<div>Hi All,<br data-mce-bogus="1">

<div>Well now that spring is here, I am resuming the rebuild of
my BJ8 engine. The engine was rebuilt back in 1999, but since
I'm doing a full resto of the car, I decided to take a look at
the engine. While all other parameters were well within spec,
the cam and lifters were damaged. Back then I didn't know much
about modern oils and the lack of zinc, and since that's the
only part of the engine that didn't do well, I am assuming
that must be why.<br>
</div>
<div><br>
</div>
<div>So I am now trying to decide what to do. I can have my cam
reground, or buy new. Since I believe it was already reground
and based on the wear, I am thinking maybe new is the best
choice. I am looking for stock or mild tune only. <br>
</div>
<div><br>
</div>
<div>I am not a pro engine builder, but I know the basics and am
not new to the process. I know that if I change something like
the cam parameters, I need to understand how that affects the
rest of the valve train. I looking for guidance on selecting
the right components.</div>
<div><br>
</div>
<div>I am considering the Welch DWR8 cam and lifter package. I
understand that I will have to machine pockets into the block
for valve clearance. I will be having the head rebuilt to
basic stock parameters as far as the valve gear is concerned.
I need to determine how to select the correct pushrods. Since
this cam is drilled to feed oil to the lobes, do I need to
make other modifications to support that feature? <br>
</div>
<div><br>
</div>
<div>So I'm looking for some feedback and recommendations from
the list. Has anyone followed a similar path on their 6
cylinder Healey? Any opinions, cautions, or advice would be
appreciated. Is this cam my best choice? Also if there are
better options to consider I'd like to hear that also. <br>
</div>
<div><br>
</div>
<div>As usual, thanks in advance for any help.<br>
