This is a 350 with a flat top pistons, and a full Holley Sytemax kit (234/244 cam, high flow aluminum heads, intake manifold). Also running full roller rockers, and using a Holley 750 carb with #69 Jets. It is running well, I can get it to idle at 600rpm even with this lopey cam. Running a TH350 tranny.

Problem is that I SHOULD be able to spin the tires off a stop, but can't. I have 35" diameter tires (Jeep), with 4.10 gears. I'm pretty sure this is not the core of the problem, but it contributes I'm sure.

I run at 2000RPM torque converter. I had a 3000 stall speed converter, but I hated revving up at every stoplight. I am quite certain that the core of my problem is engine to torque converter mismatch. I need to swap my cam for a cam with a lower RPM range (90% of my driving is 1800-3000 rpm on street and offroad). But before I do, I wanted to get some feedback.

If I do a cam swap with lower durations, should I also change out my intake? WIll I still be taking advantage of the aluminum heads? Any suggestions for a CAM? I am very much wanting a low rpm torque monster and I do not have that now.
