Detroit Rocker information?

Iíve done hours of reading on all of the major mustang sites regarding Detroit Rocker cams. Understandably, most of the threads are many years old. Iím looking for current comments from folks who still have these cars, or others who may have installed them over the last few years. My number one concern is losing noticeable low end torque. I do not want to spend $1,000 to lose low end.

I have stock exhaust manifolds, high flow cats, X pipe, 2.5 stainless cat-back, original 40ís out back, and 3.55 gears with a stick. Iím not interested in changing any of this due to state inspections in my area, and extra costs. Only interested in adding cams.

- I understand I really wonít gain any HP from these. These mod motors are way different from pushrod motors like an LS.
- I want a subtle lopey idle (not interested in dramatic, hot rod type lope)
- I want to maintain stock drivability with no noticeable low end loss
- I donít race my car in any way. I do enjoy stomping on it from time to time

So, what is your experience with these? Will I lose noticeable low end torque, especially since I donít have headers, gears, etc? Iím just looking to make some noise at stop lights when Iím cruising.

Thanks guys I know this has been beat to death, but if Iím going to drop a grand on cams I wonít want to lose my low end in the process. I've read both opposite ends of the spectrum in old threads. Some guys say there is no loss of torque at all, some say it killed their low end. What gives?

Detroit Rocker's are similar to the Ford Racing Hot Rod cams. Both recommend 4.10 gears and with an auto a 3k want noise buy some cutouts....

Unless you drive with the engine at 5000+rpm for extended periods, you'd be wasting your money on performance cams. All will cause some degree of low rpm/mid-range torque loss and in the case of Detroit Rockers, it's about 15-20lbft from 2000-3000rpm. Hence you need either 3.73 or 4.10 axle gears to compensate. On an automatic, you also need a 3000+rpm stall converter.
