Try putting ANY type of power adder on one that doesn't have forged internals. The DOHC has had six bolt mains since it was first produced. That does not stop it from spitting the internals everywhere when more than 6 psi is put on it. Yes they have great power potential when SC'd (I've seen cars with more than 700 rwhp on boost alone) but they are dammed expensive to make them last. I priced out many a 2V N/A buildup back when I had my 1996 cougar. The 2V motors have the most aftermarket support right now since there are so many cars with them. Getting a forged 2V motor that can produce approx 350 HP with good parts you are looking at more than $8,000.00 on the motor alone. For a DOHC you are looking at more than 10. Just regular replacement parts for the inside of that motor are expensive. You can go right to summit and buy an LS1 complete with everything to hook it up for less than 4K, have a baseline of 320 HP and have very far to go from there. I personally don't give a F what the badge says on the car. The only reason why my 88 XR7 doesn't have any other brand engine in it is solely based on the fact that I'm too lazy to force another brand in when my 351 fits fine. I guess the only thing I can say is that I would've first tried to get my hands on an '03 Cobra motor before forcing a GM engine in there.
It's *supposed* to have 305 hp. However put one on a dyno next to a 305 HP z28 and see which is which. I have never seen more than 254 rwhp from a 1996-1998 cobra. Likewise I have never seen less than 280 rwhp from a 1997-1998 Z28. Hell, my 98 LSC with "290 HP" has never put down more than 210 rwhp. I don't think my drivetrain is costing me 80 hp. Quite a difference from the factory rating.
