Very interesting topic, I read some of the major race engine builders have always felt that full race it all about the big bore.



One of my bucket list projects for a streeter has been a under square street/light tnt 3.950 bore on a 4 inch crank since they say ... low rpm/high tq.

In this case im not sure if im going to see any drastic changes vs our common stroker builds, but who knows.
