69 Notch Barracuda - Rebirth

Thanks. I should have clarified what I’m after. Generally speaking, from what I’m reading, it sounds like 4-hole for low end TQ, and open for top end HP. I’m after low end, so ill stick with the 4-hole for now. Summit QA said the same.

What prompted my question was watching this:
