Hi, I am new to Cobras, and have questions.

I will be purchasing a Cobra in the next few months. I prefer to get a 99-01, but mostly a 99 because of the price. I have had 5.0's and recently had a 4.6 SOHC and loved the 4.6 over the 5.0's. This time I have decided to get a DOHC 4.6. I noticed that the 99 is rated at 315hp at flywheel, right? That is 270 at wheels? If so, how can I get it up to 310 or 340 at wheels? My thoughts are for a complete exhaust, intake (cold air, maf, and tb), and cam shafts. With respect for a custom tune. Would that put the horse power levels to 310 to 340? I find that fast enough for me and very streetable.

Thank you for your assistance!

Thanks for your replies! So the heads on the 99 are crap? I'll save for 03-04 cobra heads then. Is the intake any good or do I need a new one? Will aftermarket cams for the stock 99 heads fit the 03-04 heads?
