Comp Thumper NSR 127020 Cams

[Shelby_GT_C]

If you were thinking about this mod, I highly recommend them. Just installed the Comp Thumper NSR (127020) cams. Everything went perfect and it passed emmission inspection on the first tune. So far I’m pretty impressed with them. It really pulls hard from 2000 to 6000. I'm, running Ford Racing shorties and 4.10 gears. I didn’t lose any low end as others have stated I would. Follow the link below give a listen.

Sounds nice. What do you mean by "passed inspection"? Emissions?

Yes, sir. In my Texas county you have to pass a safety and emession test once per year.
