Speedway Motors 91618016 Details

These billet aluminum adapters allow you to put a 1997-2013 LS engine where a S/B Chevy would mount. They bolt to the sides of your LS and accept standard S/B Chevy mounts. Metric and Standard hardware included.

Constructed from .383" thick aluminum
LS bolt pattern is 4 3/8” horizontal and 3 1/16” vertical
Triangular bolt pattern for the standard SBC motor mount
Locates 1.1875" forward from stock location

Note: These motor mounts may require you to move your transmission mount forward in some applications.

Application

These LS engine conversion motor mount adapters create clearance interference with the OEM lower passenger side A/C compressor bracket. The factory bracket is not compatible in this configuration. Proper A/C fitment requires either a compressor relocation bracket or an aftermarket accessory drive system utilizing a smaller, short body A/C compressor.
