Comp Cams 284HR

[strtrcr50]

Does anyone have a sound clip of a comp 284 HR idling? I'm just curious what my car will sound like if I ever finish my motor.
Here's the specs on the cam.
Lobe Center angle - 114
Intake center line - 110
_____________Intake Exhaust
Duration______284____290
Valve Lift_____.533____.544

_____________Open Close
Intake________2btdc__42abdc
exhaust_______53bbdc _-3atdc
The rest of the combo is Twisted Wedge heads with the spring upgrade, Harland Sharp S4302 rockers(anyone running these? They are suppposed to be designed for the twisted wedge heads specifically), Tubular gt40 intake, vortech s trim(12-14 lbs). I have all these parts stacked up and the wife is starting to get annoyed with me collecting parts.
For the shortblock, I am still up in the air whether to build a 331 or a 306. The car isn't going to be a race car and I suspect the 306 will be just as much fun on the street.

Also, is there any reason to buy comp high energy roller lifters at $245.95 instead of ford racing lifters at $124.95?

No one?

yeah it seems as if you don't have a tfs or ford racing cam, there's no video's around! happened to me when i was trying to find a video of a car with my cam before i put it in. i found one video with an n-41 cam, but the car had a bit more done than mine does. no vid's of n-412's though. i had to wait until i actually installed it.

i found a video of a car with an xe282hr...has a tad less duration on the intake side, but has more lift and with a 112 lobe seperation.

That cam is almost identical to the lunati 51025, except the lunati is on a 112 lsa rather than the comp 284's 114 lsa.
Should sound pretty close.
Idle and a quick rev. My 302 running a Lunati 510- Video

Not my car, video I found when looking for clip of my cam before I install it in my 331.

Anyone on this topic? Trick flow tells me there is no reason to buy the comp lifters. It's a case of I don't want to spend the money if I don't get any gain from it but if I do, I don't have a problem with it.
