Aluminum heads with lots of porting and polishing, roller cam and willing to spin the motor 7,000 rpm. That means you need to shift at 7,500 rpm, not advisable for a cast iron crank. Also the needle bearings in roller lifters need to be checked aprox. every 3,000 to 4,000 miles for wear. Just one more thing, you probably would not be happy with the driveability of such a motor on the street.


Sorry, but thats why nobody answered your post.
