Edelbrock aluminum heads
And i have to agree with you. My Dynamic 9 1/2" drove normal for the most part. However i did find it difficult in that it would maintain a lazy attitude or blow the tires out completely. Also as I mentioned earlier it was uncomfortable driving through the converter or out of it going down steep hills or out of tight corners at highway speeds.
That converter convinced me i prefer a short duration cam and stock converter at around 2300 rpm.
I'm sure most guys would take the trade to be use a bigger cam with a high stall converter and be able to blow the tires out easily.
