Need help on cam choice mild 4.8l s10
#1
Doing a mild 4.8l in a S-10 pickup, reg cab 2wd short bed. 3.73 gears in the back and a nv3500 trans
im not too concerned with loosing a little low end power as the truck should be 3k lbs or so and have short gearing, current tires are about 25” diameter. I would like to pick something that’s a little on the big side without loosing a lot of dynamic compression ratio since it’s stock compression, I may add a nitrous setup on the truck later depending on how it runs on the motor. There’s a few cams I have it narrowed down to. I think the main two are the btr stage 3 truck cam and the other is the btr stage 4 truck cam, neither are the v2’s, those specs seem like they are designed more for sound then power to me personally. I have a feeling the stage 3 would probably have a better overall power band on a 4.8l and the stage 4 might have a little more top end. Just looking for some feedback or if I’m in the complete wrong direction.
BTR Truck Stage 3- 218/224 .553/.553 113+3
BTR Truck Stage 4- 224/230 .553/.547 111+2
