I love the motor in the SPF, but it is almost impossible to hook up. I am thinking of going to some drag radials on the rear for some more traction. Even though it is probably over kill for the street, I would not change anything. It is a great running motor, and has a much nastier cam than the 427R.

yeah, buy the drag radials. It's the best thing I ever did.
