Exhaust Idle and Pull-Away

After installing Comp Cams XFI NSR Stage 2 cams and American Racing Headers Long Tube Headers and X-Pipe I made a quick video to use as a "show-and-tell"...

Honestly, the lopey sound is very subtle with the NSR cams. You almost cant tell it was cammed as far as sound goes. I did get 34 HP and 20 ft lbs of TQ though. if you are looking for jump in power, they are ok $1000 installed. Check out my Open Headers video. That was with stage 3 cams and modded heads. It's expensive... cost me $8.000 in heads, cams, Tq Converter, labor and tuning. I did pickup 135 HP and 120 Ft lbs of TQ and went 11's in the 1/4 mile.

I almost forgot... if you are chasing sound more that power... get the Mother Thumpers. I know a few people in our club who are very happy with them.

What year? LOL A 4.6L is a 4.6L. Doesn't matter what body is wrapped around it. I have a new 5.0L going in as I type. Once its tuned I'l post some new videos.

The stage III heads and stage III spr cams are not very suitable for a street car...very good gains for a track car though. Comp recommends a built bottom end for those cams I believe, check their site. I run the SPR stage II cams right now and I love them. Car sounds great man

Thanks for the Kudos and advice on the car! I am not going to use it as a daily driver anymore starting around the Novermber time frame. I want to build a really beefy track car, but still fall into the "street class" door slammer classes. It will be a slow process cuz of cash flow.

I looked into the headrequirements for the cams, but not the block. I am going to forge the bottom-end so I can get the revs needed to make the high-end power.

god DAMN those 3 valves sound awesome

@marcspaz thats funny you say the mutha thumprs because i believe thats what i am going to install. i want power but for being more a driver than a racecar i would like sound over power but i want some gains in power to. my buddy has almost the same setup i do but has hotrods so i wanted to go atleast a different cam and also maybe get a little power than him with the thumprs also thanks again

[dagoose3829]

@marcspaz thats all i want i gues i have longtubes 4.10 and just installed frpp intake throttlebody and pullies and i need some cams to really get gains from that intake. your car sounds really good though i like it i have some dyno vids dont have any yet with the intake throttle body or pullies maybe soon though thanks
