Every motor is different
Solids are a pain period. When racing 1/4 mile we adjusted a hemi after every run. Some days the motor liked a tight lash and other days we ran .004" looser than spec. Iron heads and block. Dyno time will show you which way to go. Down side is running loose and the hammering problem even when running a 15-40 race oil. If you have a great oiling system, running a little loose will give more power and let the lifter last a little longer. I have not used a clinging oil in a solid lifter motor. This sound like a good idea. Might also keep the hammering down too. I do know running tight will extend the lifter life but cut a little power. Rick L. |
