I have the 535/460 in my SPF, and have been very pleased with the overall package. It has been dead reliable, with over 8300 miles in just over two years. I drive the car every chance I get, & race it at MotorSport Ranch in Cresson Texas and at Hallet in Tulsa, driving there and home again. Needless to say, I am pleased with the combo, as I watch my friends in the Texas Cobra Club that run 427's repeatedly break something that costs$$$ to fix almost every time they try to have some fun!
