I just installed a new crate 350 in my 1956 Bel Air. I've used K&N's before and I'm looking forward to improved performance and long use with this filter on this car also. This motor is rated at 290 HP, but with new Hooker headers, Flowmaster exhaust and the K&N filter I'm hoping for a boost of 15-20 additional HP!

Nice, high quality filter, living up to K & N'S reputation. I will reccommend K & N products to every one I can.
