exclusive Greenwood Chevy Performance Parts special!
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 385 uses the proven ZZ4 shortblock and ads to it the
Fast Burn aluminum cylinder heads for 385 value packed horsepower. With value in
mind, the Fast Burn 385 uses stamped steel rocker arms and the same ZZ4 camshaft
that powers thousands of hot rods. The Fast Burn 385 is an excellent choice for
the basis of a custom engine. Its strong forged steel crankshaft and forged
powder metal connecting rods have been proven to 500 horsepower. And its Fast
Burn cylinder heads are hungry for a little more cam. 430 horsepower at 6000 RPM
is achievable by adding the HOT cam and 1.6 ratio 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.
The Fast Burn 385 is not intended for
marine use, and should only be used in 1973 and earlier pre-emissions street
vehicles or any year off road vehicle.
