poly 318

Those guys at Chrysler Power develped some new parts heads 4 bbl intake, NOT cheap but.. not sure where it is all at now Roland passed. Oem 4 bbl itake are out there but not cheap either.
The LA engine came along with a thinner casting and cheap to build. The poly had a lot of potential, but the B motor (350,361) was already there and then along came the 413, then the 426, and then the 426 Hemi. I poly disappeared about what 66??
