That's why I can't understand why anyone runs crate motors in their personal hot rod. Back 15 years ago, I used a MoPar Performance crate 360 SHORTblock in a customer's build, and even then jerked the .508" cam for a Comp XE275HL! Added Eddy heads and a RPM manifold and it rocked, but I felt cheezy even using a prefab bottom end-LOL. :)
