a moter with to much cam and not enough commpression, will have no low to midrange torque, probaly dosnt start to make power till 5000 rpms, and with that stall and those gears you arnt there that much. i would get a cam that matches your set up. first get back some low end torque, and i bet your e.t.s will drop alot
it had a bad rod bearing when I pulled it all apart stupid factory rod bolts. the motor had plenty of compression. I'm going to replace the rod bolts turn the crank and put new bearings in it and see what it does.
