Small block Chevy 350 torque specs

Figures are in foot-pounds unless marked in-lbs. Several small LS fasteners are specified in inch-pounds, and those are kept in inch-pounds with the conversion noted, so nobody reads 89 in-lbs as 89 ft-lbs.

Primary figures come from GM's own fastener tables for a Gen III (LS1) and a Gen IV (5.3L) engine, cross-checked against JEGS, Chevrolet Performance bolt kit instructions and GM service bulletins. Where sources disagree, both are shown. Always defer to the instructions packed with aftermarket parts, and to the GM service manual for your exact engine.
