Description

Top Street Performance motor mount adapter plates allow you to swap any LS engine into hundreds of GM applications, including most '60s and '70s Chevrolet or GMC pickups and cars, such as the Camaro, Nova, Chevelle, and Impala. CNC-machined, the billet aluminum adapters are precision-cut to provide a secure fit to the block and motor mount, and they've been designed to allow four positions in order to accommodate just about any set-up, regardless of headers, pan, steering pump/box, etc.

Additional details:

* Fits all LS engines
* Intended to adapt to 3-bolt engine mount used in most 1963-72 Chevy V8 applications
* 2 1/4 in. mounting range
* Available in natural and black finishes
