A Buick 350 was an underdog for sure, it powered Skylarks and Le Sabres, and that's how it was viewed, a good running 350 with great low end torque, but was never considered a "performance" engine like the Stage 1 455. What is impressive is where this engine makes that power--the torque peaked at 3,400 rpm, while the horsepower peaked at just 4,750 rpm. In the mid-1970s Buick's 400/430/455 big blocks became unable to meet fuel economy/emission requirements and were phased out, with the Buick 350 remaining as a factory option until 1980. This will help hasten the oils return to the pan. While it was officially called by Buick the "Fireball V8"[1] it became known as the "Nailhead" by enthusiasts for the unusual vertical alignment of its small-sized valves, features that were the result of putting both intake and exhaust valves on the intake manifold side of the "pent-roof combustion chamber" used in this engine series. The GS350 made its name from 1968-1970 as an absolute performance machine. Greatly improves power, torque and acceleration without affecting drivablility. But when it comes down to v8 vs v6 the 350 Buick what's a torque monster compared to the current Short stroke v6 as we have today. Performance & security by Cloudflare.

The biggest culprits are tiny oil feed holes, the main bearing oil hole not being aligned, and poor cam oiling. In 1962, the 215 was the only non-Offenhauser-powered entry in the field. As it turns out, the 350 could have been rebuilt without boring or turning the block as it was in really good shape, but in order to get the tight clearances for high-performance use, the machine work was performed. Using an oil pump thrust plate helps increase oil pressure, by eliminating cavities in the oil filter housing, as well as giving a new surface for the gears to run on, in the event the oil filter housing is worn from them riding against it, which is a very common problem.

[10] This raised the cost of complete engines to more than that of a comparable all cast-iron engine. In the mid-1980s, hot rodders realized the 215 could be stretched to as much as 305cuin (5.0L), using the Buick 300 crankshaft, new cylinder sleeves, and an assortment of non-Buick parts.
