Camshafts
Why we don't regrind camshafts
When you look through our lists of camshafts you will notice that we do
not list either exchange or reground cams. There are 3 reasons for this:
1. When you regrind a standard cam in order to increase the duration
of lift, you must remove material from the base of the cam. This would
be ok if the new cam profile you wish to grind is only very mild. But
if your going to the trouble of up rating your engine by fitting new cams
& the effort that involves, surely a profile that is significantly better
than the original is worth the extra money.
2. The base circle of the cam gets smaller & is reduced by more
than 0.04" (or 1mm) the hydraulic valve in the cam follower cannot extend
any further. It will then either stop & the follower will lose contact
with the base of the cam, or it will jack up so far it will fall to bits.
3. The most important reason is because the fault could take a
long time to show up, when it does its too late and as the base of the
cam gets smaller, the cam follower rises up its bore to stay in contact
with it. The problem you get is because the follow it so much higher out
of its bore it has a tendency to rock backwards & forwards with cam motion,
this slowly wears its bore. Eventually it can become so worn that it gets
stuck at an angle & when the cam next comes round it makes quite a mess.
Camshaft costs
All SBD camshafts have been designed in conjunction with Kent Cams and
extensively tested on the dynamometer. Because of the costs involved in
developing and testing, we charge a premium price for all our own cam
profiles. If however, you wish to purchase Kent Cam profiles from their
normal range of cams standard listings, these will be available at normal
Kent Cams prices.
All Exhaust cams shown are shortened for Distributor less use if you intend on using a Distributor please remove the 'S' from the end of part number when ordering.
*Power gains can only be achieved provided your engine has the components to complement it. E.g. exhaust manifold & system, induction system & cylinder head porting where required. If you look at our upgrade kits they will give you more help.

The
SBD 284 & SBD278 cams have been designed give about 15 -20 BHP*
over standard cams, without compromising the drivability of the
standard engine, they produce a power band of 3250 - 8200 RPM. They
can be used with the standard pistons when the valve pockets are
deepened. If used with Omega pistons & steel rods it will allow
the compression to be raised. This increases the torque across the
entire rev range and the steel rods allow the use of higher revs.
