Poly 318 Engine Rebuilding Introduction
![Poly 318 rebuild](https://poly318.com/wp-content/uploads/2022/08/Poly_318_Core_Engine-1.jpg)
In the top-right accordion menu is a detailed series on rebuilding poly 318 engines (also applicable to 277, 301, 303, 313, and 326) including performance modifications and building a 390 or 402 stroker. There are additional modifications I do not cover (main-cap girdle, oil scraper, roller rocker arms, etc.). This series is a work in progress as I build a 390 stroker for my 1956 Dodge Coronet coupe.
