thanks for the info. well the motor has alot done to it i bought it used so i dont know everything but it was built for short track racing in a late model car. it has 12.5:1 compression by the ay it idles i would say it has a big cam 4 barrel 600cfm carb clifford intake and custom headers. but i cant seem to get it to run right i might be expecting to much from it but doesnt feel as strong as it should i just want to make sure everything is set right.
