Depends on which configuration you get, I know someone that runs one around here and I'm sure its 650 or higher. He wins just about everywhere and is a Shaw Test Driver I guess it should have to HP for 40k
7uptruckracer, Mullins engines are nowhere near 40 grand for their mod engines. More like 17 or 18000 for an up front UMP mod engine. They do build a quality, reliable engine with smooth power that will win races. They also have good service when you need something done. I have had 2 of them.
