Sleeper Cam I am looking for a good stock idle cam that produces pretty good hp gains...i have looked into the Thunder Racing "old man" cam (tr115)...does anybody have any negative or positive info on this cam...or is there another cam that would be better with a very stock sounding idle...any help would be appreaciated
Yes sir they sure do. Made 390 look on the dyno. It is a kick *** cam. I am changing the set up hear soon i will be selling it for $225 so if you want to wait i will send it to you.

I've got a good Lunati cam... 221/221 .510/.510 on a 116 that made good power in the original owners C-5 that I'll sell for a 100. I just pulled it out of my engine and it's a steal at that price.

Look at this post by Patrick G on the OMC from TR. It made the same power as his TR230...

The idle on the GT2-3 is stock. If someone doesn't tell you they have a cam...you won't know it. And as far as the heads go I think they were with stock heads. With ported heads they are getting over 400

For the record, I run the Stealth Series II cam or "SS2" (224/220 .581/.581 116 LSA.) The S1 (Sanders 1) cam was my 9 second NA cam. It's decidedly NOT stealthy! 
11.20 at 121 MPH and a STOCK idle at 650 RPM while pushing 3525 lbs with 3.23 gears. I couldn't be more pleased with this cam. This was with LS6 heads (11.1:1 CR) which add about 10-12 RWHP, IMO. It dynoed 423 RWHP through an A4 tranny spinning 17x11" wheels and 315/35/17" Nittos. Your results may vary. Some people have had a less than stealthy idle with this cam. I dunno. All I can tell you is what mine does.

If you are going for a stealth setup, I'd go the LS6 cam route. If you go stealth, why spend a couple hundred extra for a little extra power. The LS6 cam has made 390 on stock LS6 heads and over 400 on ported LS1 heads. This cam, with springs costs less than $300. Compared to another "stealth" cam that is 400 for the cam, and another 300 for springs and retainers = $700. With gears or a high stall torque converter, you probably wont see a difference between the cams as you will always be up in the powerband. If you want more power down low, then a stealthy vendor cam would be more appropriate. Just remember that the exhaust system will be the major determinant as to how "stealthy" a cam is.
