all i can say i was not happy with the airgap ran much better with the victor , would pull right up to 6500 where the rev limiter kicked in / ir gap just does not flow enough for a big stroker
Probably not for a stroker. It might have to be ported quite a bit to support the airflow demand and it would need to support the demand of the heads. That might get it to support the 6500 rpm flow as well.
