Factory Forged Pistons--Which Motors Had Them?

[Dibbons]

I was curious what '60's and '70's Mopar Motors came from the factory with forged pistons?

The 70 six pack I had still had the original cast piston.

I'm fairly sure the 6 Pak pistons I had, one set 69 1/2 & one set '70, were cast. Could be wrong, long time ago. They may not have been offset, left bank & right bank, again not sure. Pretty sure they did have a different compression height though.

what about the 273 hyper pack? forged or cast??
