The final years of the Daytona with the V6 actually sourced the cylinder heads from Lotus!
So the V6 was a Mitsubishi. It was a 3.0
You are thinking Mopars first mass produced DOHC engine. It was a 2.2 DOHC engine with a head designed by Lotus.
The head actually had an issue with cracking.
It was used only in the Dodge Spirit R/T and Dodge Daytona IROC R/T(with the 4cyl engine as there was a V6 IROC)
