Mopar Muscle – October 2019

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.
