89 rs, stripped 3.23 gears, 2500 stall...Weight is around 3300 lbs.Motor is 1998 5.7 vortec..Eddy rpm airgap intake, 750 holey... got all the boltons, ignition, headers, etc...Car suspension is set up for the track...Am wondering what would be a good cam choice for this type of vehicle...Am running 700r4...Gear will be changed soon to the 3.73 area...Will be glad to provide more details if needed..Please chime in with any thoughts..Thanks very much, Tom

 

It's been a long time since I fooled with those heads but if my memory is correct I think you may be limited to around .500" lift. I had a friend running a .525" lift cam on a dirt car with vortec heads. I never saw him race but it seemed strong.

 

You need to start with a cam then build everything around it. Since you already have a lot of parts, you're going to be limited to what the cam can do with those parts. Any sub par component will restrict the potential of a cam. You're biggest limiting factor right now is the converter stall. The stall speed is to get the engine rpm into the powerband as quick as possible at WOT. Too low or high and you lose performance. You're now limited to a camshaft that will work best with your stall speed which means other parts may not be optimal.

Is this street/strip or strip only? Parts selection will depend a lot on that.
