The Enginetech OC350-R is a one-piece molded gasket that replaces early multi-piece cork/rubber designs for the oil pan-to-block sealing interface on 1975-1985 Chevrolet/GMC/Buick/Pontiac 4.3L-6.6L 262ci-400ci V8 engines for right-dipstick block applications. The gasket provides a precision-molded sealing profile matched to the factory oil pan footprint, for oil-pan-only service or as a replacement during a lower-end rebuild.

About Enginetech Oil Pan Gaskets: Enginetech oil pan gaskets provide precision-molded sealing for the oil pan-to-block interface - the highest-pressure and most vibration-exposed sealing surface on the engine. Each gasket is cut or molded from materials matched to the OEM specification: one-piece molded rubber on most modern applications, with profiles that replace early multi-piece cork/rubber designs where noted. Enginetech's part-number consolidation covers a wide range of engine families and block-casting variations with fewer SKUs, delivering OEM-match fitment without the catalog complexity.
