The 408 motor I just built for my Barracuda is 0.033 (piston is 0.005 out of the hole). Just got it running on Saturday, drove straight to the drag strip. Only made 5 passes on it (I lost in rd3). It held together and got me back home....I call that a win, lol. Ran 6.59 in bad air, on the brakes (would have been a 6.58). The car kept getting faster on every pass...even as the air got worse.
Edit: I shift at about 6500.
