High CFM heads - What would you chose?
Me either...... but Brett made 1000hp with them......and that’s a pretty high water mark.
One of the engine contest builds last year was well over 700hp with them(stock Magnum block I believe), and that build had some limitations stipulated in the rules.
I think the lack of block availability has put a damper on a lot of potential SB and BB higher horsepower builds.
