Yeah, it'll fit, and the DOHC motors are sweet, but for the money you're going to spend, you could build a hell of a pushrod motor. Damn, for 16k you could run 9s if you wanted too. If it were me, I'd leave the mod motors alone, because they're not for our cars. I'd build a big stroker, maybe with a blower, and be done. Also, there were no 2000 Cobras, other than the R, because SVT was too busy fixing the mess that was the 99 Cobra. Good luck in whatever you do.
