<span class="css_body"><font color="#FFFFFF">Cam options for
the 3.4 DOHC are few and far between. You could possibly have
Crower or some other company make a solid billet cam set
custom for your motor, but thats going to cost anywhere from
$1000-2000. The alternative is to have the stock cams reground
for a better profile. Lunati will NOT do them, same goes for
Crane. You can try another company (if you find one that will
let me know), but I am done as I dont think it is necessary
any more for my goals.<br>
<br>
The cam profile on a regrind is unknown, as they would need to
have the cams first in order to see how far they can go.
Because the stock cams are solid, there is little risk to the
cam, though you can still weaken the design. That would make a
new billet cam desired, but the cost is clearly not its strong
point here.<br>
<br>
No one has had this done that has shared the infomation yet,
so once we have specs and feedback, expect to see more here.
The only insight I can provide is based on Desktop Dyno, which
show a 20hp increase with just a 10 degree duration increase
and stock lift. Obviously they can change the lift as well,
but the duration increase is unknown. Also, its Desktop Dyno,
so real world results will vary.<br>
<br>
<b>Cam Timing</b><br>
<br>
Because the cam gears are not keyed, the options for cam
timing are nearly infinite. While this can cause a problem for
the novice trying to set the cam timing, it also allows great
flexibility for those with more experience. First, I must add
that any painted timing marks are to be ignored. To learn more
about how to set the cam timing, <a href="http://www.60degreev6.com/index.php?p=pages&pid=46">go
here</a>.<br>
<br>
<a href="http://www.60degreev6.com/images/DOHC/General/timingcover.jpg">
<img src="My%20Webs/TNtimingcover.jpg" width="150" height="100"></a><br>
<br>
Here is a picture of the 91-93 Timing chain cover. Please
ignore the spiders, I had to dig around for the cover. You
will notice at about 2 o'clock from where the pulley would be
that there is a little arrow mark. This is the stock timing
mark to set for TDC. The casting line or whatever it may be
that this arrow is set on is of particular interest. Though we
have no dyno results yet, the initial driving results are
favorable enough to discuss. This straight line marks ~13
degrees retarded from the stock timing mark. By setting the
exhaust cams for this mark and the intake for the stock mark,
a considerable power increase can be noticed on an NA DOHC.<br>
<br>
We are working with fastfwdperformance.com to have a set of
cam hold down tools made that will allow easy setup for this
cam timing. Currently, you will have to set the cam flats
perfectly flat individually on each bank for the seperate
timing. With a set of hold down tools made, you would simply
set the cam flats according to the hold down tool to the stock
arrow mark.<br>
<br>
As always, this page will be updated as more information is
made known.<br>
