Wow, that thing is amazing!!! Extremely well engineered sleeper V-8 transplant and a pure steal at that price. The time, money, labor, and effort (headaches) that went into that transplant and modification is probably way more than the stated $15K invested. A true bargain when you consider the price by AutoPro's for a converted V-8 VX (cough, cough). The power-to-weight ratio of this X-90 must equal that of a rocket ship!!!
