Genuine Gen-1 small-blocks re-enter production and will be available brand new

GM has recently announced that the original Gen-1 small-block 350ci Chevy V8 will once again re-enter production as a service replacement engine, at their Springfield Missouri plant.

Debuting in 1967 under the bonnet of the Chevrolet Camaro (as an optional high-performance engine), the versatile V8 quickly spread through all facets of the GM portfolio (even so far as Australian shores).

53 years after its release, the ‘all-new’ (in construction, not design) small-block is intended to service Chevrolet’s long-running trucks, vans and SUVs from the late-80s to the 2000s. They will be released in three variants: the Gen-1, the Gen-1e LD, and the Gen 1e-HD.

The Gen-1 is aimed at GM’s SUVs, vans and trucks from 1987-1995, while the LD and HD variants seek to service light-duty and heavy-duty trucks from 1996-2002.


The 2020 small-blocks also benefit from a new four-bolt main block which accepts a mechanical fuel pump and roller-camshaft ready as well an overall superior construction thanks to GM’s modern CNC-machining methods.

The new crate motor also includes a forged-steel crankshaft, harmonic balancer and new valve covers, oil pan and timing cover; and are covered by a three-year/100,000-mile warranty.

No word has come from GM regarding pricing or further specification details such as compression, camshaft profile or even power output – but the engine does appear already available to order on GM’s genuine parts website, and should be welcome news to Chevrolet restorers around the globe.
