We have two of Keith Crafts 408W in our club. They make 530 plus hp and 540 plus tq. Coach Mike has several thousands of miles on his, three years of driving year round. No problems. Very street-able motors, meaning they idle correctly, do not over heat, no
oil leaks, no problems. Just drop in and drive.
I picked up the last motor a couple of weeks ago. 408W 531 hp & 540 Tq, cost $8375. If you will add up the cost of the parts your going to buy and the machine work, you will spend close to $8000. Keith uses parts that he has proven will work.
His shops are clean and orderly. He has all the machines needed to build a motor. We have five of his motors in our group and everyone loves them.
I can't say enough about the horsepower and dependable of his motors.
Check him out.
