I'd like to install a cam in my normally aspirated LS1, can someone out here in GOATLand give me a few pointers as to which numbers I'm seeking out I have no idea what "lift", duration and all those other numbers mean, my cam tech knowledge is rather limited. It's a street car but I do get in some time at Cecil county Dragway and the few times I've gotten seat time the results were abysmal. I was told a mild cam & a custom tune along with the headers I already have installed my numbers should get better. I was going to purchase one from a gentleman on here but it was just to radical for the street. PLEASE HELP!!!!!

I assume you want to keep it a daily driver? Also, is it a manual or automatic? What gear ratio? These are just a few of the questions you need to answer. Others....do you plan to get into the heads down the road, how about an intake manifold, will you be considering some kind of forced induction? Here is an old rule of thumb, keep the duration at 0.050" below 220 and you will have a very streetable daily driver motor with much more mid-range and somewhat better high rpm power. Little to no jerking or bogging if you sometimes lug the motor. As far as lift goes, for a primarily street driven car you want to avoid dual valve springs. They bring higher seat pressures that wear out valve train components. Keeping lift under 0.570" allows you to stay with upgraded single springs. I would also recommend a lobe separation angle of around 114 degrees. Now for the bad news.....pretty much everybody that responds to your post will have a different recommendation. My signature shows what I've got in my car.

I'd look at something like the TSP 224R. IMO I wouldn't waste my time going with something less than 220/220. Keep lift under .600.

Stick or auto?

There's a lot more to it than any single item, hence this form is required to order the "correct" camshaft profile.

Here are my cam specs, Cam - [email protected], Lift .568", LSA 114 . I have a heads/cam/Fast 102, 3200 stall, but perfect for road car and few visits to the track.

I'm happy with the Summit Racing Pro LS Stage 2 cam I recently installed. Stock T56 and stock rear as well with plenty of other bolt-ons.

I went with a EdC 220 cam. Made more torque everywhere and just a touch less HP at the top than my old 228/232 Comp Cams did. It's a baby cam that acts like a bigger cam. Easy to tune and great to drive.
