I got my Cobra back last week after a year in the shop. Read carefully and avoid the mistakes I made:
I got the itch for more HP last year (480 wasn't good enough), so I decided to port the heads and replace the cams. I took the heads to FPS in anaheim, CA (DON'T EVER GO THERE). the 'Two weeks' turned into three months. The "i've done dozens of 4v cobras' turned into 'yours is the first and the porting program on the CNC needs to be written.'
Finally, after more than three months I got the heads back, took weeks to install, and the car wouldn't start. The cams were all jacked up and couldn't get them dialed in. The CAM cards I got from FPS WEREN'T EVEN FROM MY CAR.
I took the car to Superior Automotive to fix. They couldn't do much - replaced the CAMS with stock (wasted $3K), but the car had LESS power than when I started, even after the port job on the heads and the Eaton. Superior retested the heads, and they were REALLY SCREWED UP, as were the pistons by now from detonation.
I had them rebuild the engine, which took about 5 months (waiting on this and that, etc). While I was waiting, I ditched the ported apton and bought a Kenne Bell.
I had the car for a couple days last week (finally), great #'s, but more tuning needed. Took the car back because it was puking fuel out the tailpipes and it was running like crap until you pushed it past 1/4 throttle - ran like hell then.
So, new MAF sensor and looks like some bizzare electrical problem. I should get it back in a day or two (yep, heard that before....)
1/2 throttle on the way to Superior allowed me to smoke an '05 GT from 70 to about 110 (If Joe or Don ask, I babied the car the whole way back) - in 4th gear (never wen't past 4000 RPM, honest).
