Here's the specs for this motor and all engine modifications . The current motor is a 393 stroker. Dynoed as of 7/22/03 with 420.6 rwhp and 470.8 rwtq. Check out the dyno graph below. That is with nothing ported and couldn't turn the timing up higher due to pinging which is was caused by the fan which wasn't enough to cool the motor and the high compression. Here is the setup below.
