Fits On/Installation Notes:
Big-Block performance built from our tall-deck LSX block!
One of the most legendary engines in muscle car history was the
Chevy 454 Big-Block. With the tall-deck LSX Bowtie block, GM
Performance Parts engineers were able to build a 21st-century 454 with
the latest technology and it requires no more space under the hood
than a production LS engine.
The LSX454 is filled with an all-forged, super-tough rotating assembly
and features a pair of our new, deep-breathing LSX six-bolt cylinder
heads. It also comes dressed with great-looking, orange powder-coated
valve covers with engraved LSX454 logos.
GMPP delivers the LSX454 without an intake manifold and other
accessories. With a carburetor and high-flow GM Performance Parts
intake manifold, the LSX454 is good for about 620 horsepower and
600 lb.-ft. of torque or about 580 hp and 600 lb.-ft. with fuel injection.
590 lb.-ft. @ 4,800 rpm
620 hp @ 6,200 rpm
