If I could be around 700 I would be happy. We can run a vac pump also to help squeeze the most out of it as possible. Rules state the engine must match the truck. I already have the chassis done so I’m stuck with Mopar powered which I would prefer anyways. I could step up to the pro stock class that allows aluminum heads and 485ci. My buddy runs a ford in that class with kaase p51s that makes 950 and is getting the new sr71s next year. They really limit the Mopar heads in that class as well. No b1s. So victors or indys would be the better choices for it.
