Shoud I relieve my block

[38 coupe]

Is this a decent summary of the information in this thread?


1 - Below 4500 rpm there is no benefit to a relief.

2 - For motors built for competition use a relief can help, but must be carefully designed. The rpm range of competition will heavily favor whether a relief is helpful or not.

3 - For all out high rpm use such as land speed racing a relief is necessary.
