The 57s on the car are for sale, i never ended up using them, but im asking 750 shipped for both firm, should support 700hp easily on a mod motor or sbf... i decided to go bigger since when this engine pops or the trans goes, i will probably start a 5.4L 4v auto swap. they are t3/t4 journal bearing, .63 a/r, with a 4 bolt t3 outlet
