The 413 is an RB engine not a Hemi (chrysler neve made a Hemi displacing 413 CI).

Unlike some of the other Ploy engines the 318 will not accept Hemi heads.



I undrestand that.
They quit the Hemi in '58 and introduced the Wedge head motor in '59 till '64 when the Hemi came back as the 426 Hemi. But alot of people call the earlier 413 Hemi's.

The wedge head engine was built in 350, 361, 383, 400, 413, 440

I was thinking of the earlier poly motors.
