I smoked those Gen 3 Hemi tanks with my little 415" LA stroker on pump gas, lol, even at the track I gapped those turds so bad it was embarrassing......NEVER IN MY LIFETIME will I ever have a Gen 3 Hemi in one of my real hot rods because I don't like a smooth idle and I also don't like how ugly that engine is and furthermore it reminds me of what Gov't builds with all their emissions and computer this and that and I detest it....bonus on the cake is I can flat beat 98% of ANY Gen 3 Hemi to line up on a dragstrip.
