Does anyone know why they chose to put resonators on the Hemis?

[hemigeno]

Yes - and I don't think they cast any blocks during 1967 at all (or very few anyway).

I have heard that too. My block was cast in February 1968.

Back in 69 Dad bought a new Newport Custom that had a 383 in it, It had a resonator.

Chrysler...typically more demanding buyers who didn't want the NVH.

Wasn't my idea... Dad had a 66 GTO w/ 389 tri-power and a 4 speed that I just loved, but he traded it in on a 67 Ford Pickup. When the 68 Chargers came out I wanted him to get one and he probably would have traded in a 63 Chevy Biscayne but mom put the stops to that because she wanted a family car, so he ended up buying the 69 Chrysler a year later. At least he got a Mopar.

What year was it again that a bunch of Hemi motors were cast & used up for a couple years worth?

[Ghoste]

I think it was 1966.
