2011 - Crane Cams

1992-1996 305 (5.0L)- 350 (5.7L)
LT-1 & LT-4 V8
Additional changes in 1992 resulted in the Gen II, or
LT-series of engines. Reverse cooling, front mounted distributors,
a different timing chain and gear set, and other
improvements resulted in greater power potential and reliability.
All of these were hydraulic roller camshaft and lifters
equipped, incorporating the tall lifter bores. The Crane
Cams 10-prefix is again used for these engines. On applications
where higher than stock lift, or small base circle camshafts
are used, our 10535-16 or 11532-16 hydraulic roller
lifters should be used.
Mechanical roller lifter camshafts and components are
offered, in standard or Iron Gear versions.
1997-2010 4.8-5.3-5.7-6.0-6.2-7.0L
LS-Series V8
A clean sheet design for the Small Block, this new engine
has virtually no interchangeability with the earlier engines.
Crane Cams 144-prefix designates these camshafts and specific
components. The camshaft has large 55mm (2.165”)
diameter journals, three bolts to attach the cam sprocket,
and no distributor drive gear. Hydraulic roller camshafts
and lifters are standard.
LS1 and LS6 engines have a camshaft position sensor split
ring incorporated into the barrel of the cam, near the rear
of the camshaft. LS2, LS3, LS7, and L92 engines have the
camshaft position sensor incorporated into the camshaft
sprocket. Our camshafts have the sensor split ring on the
cam, and can be used in either version. The standard firing
order is 1-8-7-2-6-5-4-3.
The LS3, LS7, and L92 engines are originally equipped with
camshafts that have a single bolt to attach the cam sprocket.
Our camshafts can be installed in these engines if the
proper three bolt type cam sprocket is used.
Standard rocker arm ratio for these engines is 1.7:1, except
the LS7, which comes equipped with 1.8:1 rockers.
Again, when using camshafts with greater than stock lobe
lifts (or reduced base circle diameters), there can be a danger
of the lifters dropping out of the alignment blocks.
Crane Cams offers specific long travel lifters to prevent this
occurrence, with our 144536-16 steel billet hydraulic roller
lifters. Long travel mechanical roller lifters 144511-16 (that
use the standard alignment blocks) are also available for
those demanding the increased RPM capabilities of a
mechanical roller camshaft (available on special order).
We’re constantly adding to our product offerings for this
family of engines, as its popularity continues to grow. Heavy
wall pushrods, stud and shaft mounted rocker arms, valve
springs, retainers, and steel billet valve locks provide performance
and reliability improvements that you will find
throughout this catalog.
1996-2010 SB2 V8
Designed specifically for racing applications, and never
installed in any production vehicles, the SB2 engine has a
unique cylinder block and cylinder heads. Although the SB2
heads have a different valve layout from other members of
the Small Block family, they can also be installed on a conventional
262-400 type engine, provided many other
changes are made, among these being the camshaft (use
our 138-prefix camshafts for this application as noted earlier).
An SB2.2 block has staggered lifter bores, similar to the Big
Block Chevys, straightening the pushrod angles for the
canted valve SB2 series of cylinder heads. Our 123-prefix
camshafts have been created expressly for these engines.
Steel billet roller camshafts are offered with Large Roller
Bearing (50mm/1.969”) LRB – suffix, and 55mm (2.165”) 55J
–suffix options. As these are usually produced for specific
racing applications, we custom grind them per order to
insure the latest cam lobe design technologies are used.
Roller lifters are offered in standard .842”, .875” and .904”
diameter. Any of these are available with appropriate pushrod
seat offsets as required by the cylinder head preparation
that was performed.
