Hello all!

I am currently overseas in the Middle East. I have an RR planned this summer and am looking at picking up a few mods to put on when I get home.

I was reading Fastman's website and he lists 2 different TB used on the 5.7L from 2005-2012. One ending with 801 and the other with 847. Since I am not home to look for myself, does anyone know which one is correct? Was the 801 used on certain models only as well as the 847?

I don't want to order the wrong one.

Don't know about Fastman but Modern Muscle TB's are CNC'ed units, with dyno results from Hemi specialists. 85 mm and 87 mm are available. the 85 is variable diameter and runs on stock tune, while the larger is straight bore and requires custom tuning for WOT A/F.
