Depends on cam size, valve size, compression ratio, and more. That being said, you could have anywhere from 200-450hp!

You might slaughter an LS1 or you might get beat by an Acura Integra.

Need more info.

[spdjnky_42]

Probably around 320-350 rwhp. Thats close to what I had in my 78 and it ran somewhere in there..

[chrisblais]

how to determine cam size valve size compression ratio? and all those goodies

[74stang2togo]

Realistically 200-300 horsepower. If you wanted me to guess my best guess on the info provided I'd say about 250 horsepower at the flywheel.

stock cobra II came with 140, so more then 140. Id say the average horsepower for a lightly modified 289(302) would be around 250. with a potential (conservitivly speaking) of 425 or more depending on who builds it and how much you spend.
