Can you have the engine shipped out? Maxwell Power has really impressed me and have been building engines forever. Their attention to detail is amazing....they build Subaru engines for car and for airplanes. The same detail and attention is given to the automotive side as is to the airplane side.
If you want to take the entire car and have it built and tuned all at once Topspeed in Atlanta is the guys who take care of my car. They have built several very impressive setups that are proven.
