The motor I got rom them (a 484fe) burned
oil and fouled plugs from day one ( see my post dated 12/24/02 ). After no satisfaction and alot of runaround from Bill,I ended up pulling the motor to correct the problem. I also discovered that the valve springs were to weak for the cam they had installed according to the Reed camcard they sent with the motor, causing the valves to float. The new motor which I did myself runs great.
Oil consumption is about 350 mi. a qt. But the main thing is the plugs run clean with no fouling.
