Setting the Stage
To alleviate any concerns about the lifter bores, Bruce epoxied in a brace from the front of the lifter valley all the way to the rear. While lifter bore support was the primary reason, Kent also carefully molded the epoxy to form oil drainback routes from the heads to the pan (arrows). This keeps the oil off the spinning reciprocating assembly. There are aftermarket bolt-in braces available to assist the lifter bores, but they do not address oil drainback at all. With oil control being a major issue on all performance engines, but especially on Buicks, these mods are critical.
