Poll: which cam for power under curve?

1) How did you manage to use the stock retainers with dual springs?
b) What is your lifter preload with the smaller base circle cam and stock pushrods?
III) How did you manage to find the . for your decimal point, but not anywhere else in the whole post?
it's all about the fine details if u wont it right the first time
Back on topic, the smallest cam should offer the most power under the curve, based on its VE's.
If all the information in your signature is correct, I would ask why you would change cams for any of the ones that were listed? The 232/234 cam would stand to make the greatest power increase, but is far from an area under the curve cam. In my honest opinion, you would get everything you want and more out of a good set of heads. I know that wasn't what your post was about, but that would boost your DCR and give you a major enhancement to your area under the curve, and still add power all over the place. Just installing a pair of stock (unmilled) LS6 heads with a .040 thick head gasket will suffice, and shouldn't cost you much more than the cam would. That setup should add at least 20 hp at peak, and possibly even more torque on the low end. If your budget allows more than that (ported 5.3 heads, or stepping up to an aftermarket casting) you stand to gain even more.
What LSA is your cam ground on, and how much advance is ground in?

The more I read about cams, the more I learn . . . .
and sometime I am even more confused
I think I will just tell the engine builder what I do, and what I want the car to do. Then let him do his work.
Tending to lean with the GMPP Grand AM Cup & Speed World GT cam #88958606
239/251 570/570 106 LSA to a 105 as below.
"For best torque, install the intake centerline 105 for best power install at 107."
and the GMPP LS6 Heads #88958622 also the Grand AM & Speed World GT Heads

that is exactly it. being cut on a 106 ICL made it very hard to tune.. Have some tuning issues! I may put thinner head gaskets on to bump the DCR a bit

At 3000 rpms' its about 365Ft-lbs. Thats really good low end power IMO for a 347

DCR or SCR v. Overlap Not sure how this cam falls into a thread about best area under the curve. Just look at the overlap on this cam. It was designed as a competition RACE cam, not an area under the curve street cam running low compression stock heads.
Patrick,
Does the combination of DCR AND SCR affect the amount of overlap you choose in the cams you recommend? Looks like you like to make appx 8.5 DCR?
Or what max DCR are you comfortable with on pump gas? How much overlap goes with that DCR?

Just curious but, I have an LS1 car with all boltons except a stall(next week) and I street race mustangs all the time. We are even for about 4 seconds on the freeway(342 gear) before I pull away. I want heads and cam that will jump away and keep pulling. It is a TransAm conv. but I do not want to wait until 6000 rpm to pass. Been looking at 5.3 heads for a little compression and maybe a medium size cam(rough idle preferred) , but not sure. A lot of the shops say big cam , but do not want to wait for really high rpms before power. Installing a 3600 Yank And a 150 shot soon, but not sure about heads and cam. Any help would be greatly appreciated. Thanks.
