The Buick Nailhead

Buick’s legendary V-8 engine from the mid-fifties to the mid-sixties is often called the “nailhead” motor due to its long, thin-stemmed valves with small diameter heads that resemble vertical rows of nails. The first Buick nailhead engines (debuting in 1953) had a 1.75″ intake and a 1.25″ exhaust valve, and even the later Wildcat 401 nailhead V-8s from the mid-sixties had valves that were much smaller than those used in Chevrolet engines at the time.

Rising values have made nearly any GTO in reasonable condition a good candidate for restoration. However, even the best paint and body work won’t look correct if the original window trim and molding pieces are scratched, rusted and dented.

About twenty-five years ago the era of modern crate engines began with General Motors (GM) release of the “H.O. 350,” an all-new, high-performance small-block engine assembly that blended the best of old and new technologies through the use of hydraulic-roller cams and aluminum cylinder-heads. For perhaps the first time, the “ZZZ” stamped blocks made it as cost-effective to buy a fully assembled crate engine as to build an equivalent engine from speed shop parts. In 1990, those first ZZZ crate…
