exclusive Greenwood Chevy Performance Parts special!
Our lowest priced performance crate engine, the 330 horsepower 350 High Output doesn't sacrifice power or durability, it just pumps up the value. With its 4-bolt main block, nodular iron crankshaft, forged steel connecting rods and light but strong cast aluminum pistons, this engine screams durability. Add to the strong foundation a pair of 64cc Vortec cast iron cylinder heads and a dual pattern camshaft with just a bit of a "lumpy" idle, and you've got the muscle car small block that you've been looking for. Dressed to impress with chrome valve covers and front timing cover, this engine will look great between the fenders of your favorite street rod, muscle car or grass roots racer.
The cylinder heads on this great little performer use 1.94" intake and 1.50" exhaust valves that are sprung with 1999 corvette L31 valve springs. The 64cc chambers yield a healthy, yet streetable 9.1 to 1 compression ratio.
The cam is a modern dual pattern interpretation of the old '65 to '67 corvette 327 cam. But with more lift and duration on the exhaust side, it does a better job of clearing exhaust from the combustion chamber. We also decreased the duration and lift ever so slightly on the intake side to build more cylinder pressure. The result is a cam that makes great torque and horsepower with the 350 HO's 9.1 to 1 compression ratio.
Add the new dual plane intake manifold GM# 12366573, 650 cfm carburetor, HEI distributor, balancer, water pump and exhaust manifold or a pair of headers and you have an outstanding muscle motor with a broad, smooth torque curve and an honest 330 horsepower. This manifold has four bolts, not six, to attach it to the cylinder head. Older six-bolt manifolds will not fit the new Vortec heads.
The 350 HO is not intended for marine use, and should only be used in 1973 and earlier pre-emissions street vehicles or any year off road vehicles.
