Blueprint crate engine
I would go with the big power one, I never understood “this has too much power” If it runs on pump gas there is no reason not to. You don’t like the mileage, don’t push on the go pedal so hard. It will help with the highway gears that are probably in the 8 3/4”. There is no reliability issues with a traditional small block stroker and lets all be honest, she is definitely big boned! :):)
