Have purchased both a reman and new from Performance Improvements for our 1976 Olds 350 . They come pre-set for mild street builds . Very little tuning needed. If you have a vacuum gauge you will have a nice idling engine in minutes once installed. Both the factory reman and new carb performed excellent. I would recommend these carbs for any mild V8 small block, do yourself a favour and purchase a vacuum gauge while your here, it will come in very handy .
The carb is not being installed until spring.
