High-Lift Hydraulic, Solid and Roller Cams can add an excessive amount of stress to the conservative Buick lifter bores. Ensure your block against lifter bore breakage by incorporating this structural item. The TA lifter bore girdle is a structural unit, just like our block girdle. It is made from 1-1/2” steel bar stock machined to fit precisely into the lifter valley of the block. The lifter bore girdle uses adjustable load bolts for each lifter bore to ensure proper support to each lifter boss. As with our block girdle, once installed, the lifter girdle becomes an integral part of your engine and is bolted in place. Far better insurance against lifter bore breakage than that found with putties and metal plates. Plus the TA Lifter Bore Girdle does not pose a possible debris problem that can happen with putties. Installation will require assembly, which includes fitting, drilling, tapping and welding.
Developed and proven on Mike Tomaszewski’s 950hp normally aspirated, roller cam 532 cid engine. And now considered by many as a mandatory upgrade when race preparing a Buick 455 Block. Recommended for most roller cam combinations and higher end hydraulicand solid flat tappet combinations. Please call for more information.
