It's come time to replace the cam in my 350. I'm looking for some increase in performance while keeping good gas milage, idle, and overall drivability. I'm keeping the engine pretty close to stock but with forged flat top pistons. Summit's compression calculator estimates a ratio of 8.8:1. I plan to bolt it to a th2004r trans with a stock torque converter which I believe has a stall speed of 1800. It's going in a car that weighs around 4500 lbs and has a 2.93 rear end. I do not want to change rockers and I already have stock length pushrods. So far I'm looking at these:

Lunati Voodoo 256/262 - http://www.lunatipower.com/Product.aspx?id=4214&gid=258
Comp Cams Xtreme Energy XE262H - http://www.compperformancegroupstore...DSCAMHydFlatXE
Comp Cams Xtreme Energy XE250H - http://www.compperformancegroupstore...DSCAMHydFlatXE
Which would be the best choice for a daily driver? I am also open to other suggestions.
Thanks

The 2004R D9 converters flash around 1900 rpm, much better than the TH350 converters which flash around 1600 rpm. I have a 9 to 1 350 with a 214/214 110 LSA cam that had a 2300 stall 2004R and 2.78 gears. It would lay rubber for a 1/4 block, now with the 1600 stall in front of a TH350C, barely lays rubber at all but accelerates nicely through the rpm range. I have upgraded springs on my #6 heads, you will need new springs and retainers on number 8 heads to match the cam. Are you running on the computer?

I am replacing the springs and I am not using the computer in the car.

Probably that first Lunati cam, being single pattern and a 112 LSA but I am no expert. If they are #8 heads, get them to use a bowl cutter under at least the exhaust valve, then they will flow what early heads flow.
