sorry guy about being late there is only one company in the usa with cams for the 4.0 german v6. sadly they are custom regrinds but still done by a very highly well known U.S. cam company. and boy do they work.
the company has a v6 they built for a guy in CT. that has been run to 440rwhp with no nox. only thier long block and a stage 3 procharger kit.
