Sweet sounding truck! I moved this to the Racing and High Performance area for you.

hotrod 80 · 01-14-2014, 02:07 AM

Sounds great

MashTheGas 72 · 01-14-2014, 01:17 PM

Hey Expat. How is the power with this Cam. I've heard there just for sound. I was looking to by one myself, but didn't know about the power issue. Boy it sure sounds awesome.

Expat_dude · 01-14-2014, 06:40 PM

Seat of the pants it feels just as strong as the solid cam set up. It sure revs better!

MashTheGas 72 · 01-14-2014, 11:02 PM

That's great to know for sure. I'm definitely looking into that setup. Thanks for letting me know.
