350 Fast Burn With Some Real Power
Specification
Sheet
 |
GM Part # 12496769
385 HP Long block
$4750.00
With more ZZZ through ZZ4 crate engines sold
over the years than any other high performance crate engine, it
only makes sense that GMPP would continue to improve that
successful family of engines. The new Fast Burn uses the proven
ZZ4 shortblock and ads to it the Fast Burn cylinder heads for
385 value packed horsepower. With value in mind, the Fast Burn
uses stamped rocker arms and the same ZZ4 camshaft that powers
thousands of hot rods. The Fast Burn is an excellent choice for
the basis of a custom engine. Its strong forged steel crankshaft
and forged powdered metal connecting rods have been proven to
500 horsepower. And its Fast Burn cylinder heads are hungry for
a little more camshaft, approximately 425 horsepower at 6000 rpm
is achievable by adding the HOT cam and 1.6 self aligning rocker
arms.
Value priced small-block power, great durability, easy power upgrades.
It’s all that and more from the "More Than Just Power" people at
GMPP. |
