HELP with cam.....
I used a Vinci highperformance accelerated lift camthat gave a larger torque gain but also a large big end HP gain. The cam works for my setup but make your own decision based on what you want out of your baby. Gary
It will definitely change the nature of the car. Choose wisely for it is the one component on the motor that can make a world of difference..... good or bad. Give the info to your chosen vendor on here as to your desires and expectations and you won't hardly go wrong. a search on ls1tech.com has plenty of info and dyno results.
Cams (and heads/cam combos) typically move your peak power higher on the rpm band. How much more power and where it appears depends on the specs of the cam you choose.
I've been learning about cams for years and I still don't understand it all, simply because there are so many variables. But basically a "milder" cam will have less lift and duration than a "wilder" cam.
If your car is a daily driver (like mine) and you only plan occasional (read: once every few months) track days then you'll want a streetable cam. Something like LGs X3 cam or lower. The X3 would probably be the limit for your needs. Anything else and you're moving more towards a primarily race setup instead of daily driver.
To get the low-end pickup you desire, consider a rear-end gear swap. If you have an automatic with a performance axle then you're at 3.15 final drive ration. If you have a 6-sp then you probably have the 3.42. Depending on what you want out of your car, upgrading from a 3.15 to a 3.42 is pretty fun. I use the stock 3.42 in my 6sp LS1 Firebird and it is quite fast. Going to a 3.73 would be even more fun. But at this point you begin to effect mileage and long-term wear because your motor will always be running at higher rpms than before. Folks who run at the track a lot may go to a 3.90 or even a 4.10. Those ratios, especially the 4.10 are borderline extreme. I've known several folks running F-bodies and Mustangs who went the 4.10 route only to pull back to a 3.73 for driveability.
One more thing, don't forget that installing just a cam is (IMHO) shorting yourself. You already have a good muffler system and a good induction system (the Blackwing is awesome). But for a decent (yet reasonable) chunk of change you can get heads and long tubes too. Only then will you realize the maximum benefit of the cam you install.
Hope that helps!
