Engine Component Specifications

Here at Superformance for more than 36 years; we have been building performance engines using only premium "brand name" parts. To make things simple for our customers we offer an extensive range of 'Turn Key Engines' meaning that after installing one of our 'Turn-key's' you only need to connect up your radiator, transmission, fuel and power and you are ready to drive.
All of our Turn key Engines are run in and come with a metal stand for storage and transport.

This particular Bowtie Phantom Engine is one of our starter engine packages ideal for guys and gals who want to cruise around town with their big old chevy 8 pulling them along. Not as much power as our Bowtie Stroker 450HP 383ci or our Mental 600HP Supercharged Bowtie Engine options but still packs a punch and gives off that classic 350 look and roar.
