I don't know that you would pick up much more HP with the AFR's to justify the cost. The cam will run you in the $300-$400 range. A lot of people change the oil pump when they pull the cam because it has to come off to do the cam. Depending on mileage you may want to change lifters. You will need to throw a set of pushrods in no matter which route you choose. I would also toss in a set of headers if you don't have them already. Also don't forget to save some money for the dyno tune. In all things start to kinda count up and since different shops charge different amounts for the parts it is hard to give an exact number. Also are you planning on doing the swap yourself or letting someone else do it. BTW 500 at the crank is not very hard to attain since it is more like 400 at the wheels. Is the car a stick or automatic.
