Hi, I have a 18' 89 seaswirl with a 5.8L and a OMC Cobra drive, I stupidly screwed the clutch dog and have to replace the lower gears in it I should have replaced the shift cable when I overhauled the gimbal and u-joints... 
I am going to replace the gears with the heavy duty ones and I would like to stroke the engine and aim for around 350Hp... Is this a bad Idea? Am I going to start breaking other things.. I have seen other cobras in the paper with 383 strokers apparently at 360hp. Has anyone done this who can tell me if the drive is going to handle it.
Thanks for any insight..
