RHS LS ALUMINUM
RACE BLOCK
Racing Head Service's LS Race Block
is designed for added clearance and
customization. Available in both standard
9.240-inch (part#54902) and tall 9.750-inch
(part#54901) deck heights with an extra-
thick deck surface of .750-inches. The RHS
block features a raised cam centerline and
priority main oiling via an oil galley that is
shifted outboard to allow rod clearance
for a much larger stroke 4.600-inch while
also minimizing windage in the crankcase.
The cylinder walls are Siamese cast with
press-in spun cast iron liners. Cylinder
liners are available in both standard deck
(5.67-inch/5.87-inch–same as the LS7) and
tall deck (5.94-inch/6.38-inch) lengths. Also
featured is a six-bolt head design with a full
water jacket around each cylinder.

TCI AUTO-X GM 4L60E
TRANSMISSION PACKAGE
Although the TCI Auto X Transmission
Package is not a bolt-on component to
an LS engine, it does compliment any LS
engine by providing engine braking for
GM 4L60E applications. The kit includes
a TCI EZ-TCU along with a paddle shifter.
According to TCI, off-road competition can
utilize engine braking when slowing down
to enter turns. The TCI AUTO-X GM 4L60E
Transmission Package offers crucial engine
braking capability in first, second and
third gear when the shifter is placed in the
drive or third gear position. Upshifting and
downshifting can be controlled with the paddle
shifter while the EZ-TCU is set in manual mode.
However, when the shifter is placed in the
overdrive position the transmission will operate
without engine braking enabled.
