Trick Flow ups the ante of big block Mopar performance
with these PowerPort
®
270 cylinder heads. They
feature raised 270cc Max Wedge-style intake runners
that provide a straighter path to the valve for greatly
improved airfl ow over factory Mopar heads. Then
there’s the PowerPort 270’s other standard features:
A356-T61 aluminum construction, CNC Competition
Ported runners and chambers, 2.190"/1.760" stainless
valves, beefed-up rocker shaft bosses, PAC Racing
Pacaloy™ valve springs, ductile iron valve seats, and
bronze alloy valve guides.
For the fi nishing touch, the heads work in
total harmony with all factory-style big block
pistons, roller rockers, and headers.
Track Heat
®
Intake Manifolds
Just oozing high performance, these high-rise single plane Track Heat intakes
feature a one-piece spider-type design with extended, high-fl ow runners and raised
plenum fl oors to signifi cantly increase power and torque in the 3,000-7,000 plus
RPM range. Other bonuses include bosses for nitrous nozzles and extra material
for custom port work.
Cast Aluminum Valve Covers
Treat your build to cast aluminum valve covers! They are made from durable
A319 aluminum, which is much less prone to fl ex and distortion than stamped steel
covers to prevent oil leaks. Plus, the covers clear most roller rocker arms, have
added clearance for the distributor, and can be drilled to accept breathers.
Track Max
®
Camshaft
Get even more power boost with a Track Max camshaft. It is dyno-proven to produce
signifi cant power increases over the entire RPM range, not just a particular RPM.
Your Recipe for Big Block Mopar Performance!
New heads are just one component of the horsepower recipe. To make it complete,
youÕre going to need some more ingredients.
