Guys this is not my area, but my dad has a 7.3 f-350 with a hpop and stage 4 injectors and. A garret 4inch turbo(forgot what its called)tranny fuel pump and beans custom tunes.
This motor has only 8000miles
He raced against his stock 06 viper and ate it...literally...ate it. I didn't believe that the guy driving the viper was shifting right but he said he was booking it. That 7.3 was going over 120mph because that truck picked up its butt and moved. I couldn't believe it but he did!!!! He beat a viper!!
So 7.3 guys your race lives arent over
I have pics of the truck on my profile
