NOVEMBER 2019 II CHEVY HIGH PERFORMANCE 21


10 | A tapered ring compressor is used to install the SRP pistons in their bores.
This style of compressor is highly recommended for pistons using modern,
thinner rings.


11 | The Comp hydraulic
roller cam is lubed up
and slid into the block.
This is an XFI grind,
which has very quick
ramps to maximize
its short duration.
The specs come in
at 210/218-degree
duration at 0.050-inch
lift and a respectable
0.560/0.555-inch
valve lift. The cam is
ground on a wide lobe
separation angle of
113-degrees, which
will provide good idle
vacuum.

12 | The timing set is installed and a thrust button is used to control camshaft
endplay. This butts up against the timing cover and keeps the cam from walking
back and forth.


13 | A timing
wheel is used
to verify true
top dead
center (TDC)
on cylinder
No. 1. Often,
aftermarket
timing covers
and balancers
can be slightly
off, so it’s good
to find true
TDC.

14 | The timing cover is installed with a fresh gasket and tightened in place.


15 | A Summit
Racing oil pump
will provide
pressurized
lifeblood to the
engine and a
Summit oil pan
seals the bottom
half of the
engine.

17 | The Comp hydraulic roller lifters were soaked
in oil overnight and then installed into their bores.

16 | Next, Summit
Racing aluminum cylinder
heads are installed on
top of quality MLS-style
gaskets. These heads
feature 2.02/1.60-inch
valves and high-flowing,
as-cast ports. The
compression ratio will
come in at 9.5:1 with their
64cc chambers and the
SRP pistons.
