The 318 Poly has nearly the same block as the 318LA, the difference is in the heads, crank, cam oil pump and intake exhaust manifolds. The Poly is a Hemi with one row of rockers removed. If you had a Poly and now need a refresh, you'd be much, much better off to re-build the Poly. More torque, more horsepower and better fuel economy, plus nothing sounds as good as a Poly.
