2008 496 ho life expectancy

According to my builder, my 400 hour 496 MAG looked like new inside apart from the bent connecting rod due to reversion. After the rebuild, including .030 overbore with new forged rods and pistons, the boat runs the exact same speed as it did before. Nothing was gained over a fresh, slightly larger cubic inch engine over stock with 400 hours.

Yes, I know. I spoke with Raylar (Larry) before the engine was rebuilt (we ended up not going with any Raylar parts) and wasn't too thrilled with bumping up fuel pressure with his cam. Then contacted an OSO member selling HO cams but in the end decided to leave it be. It is a shame that these aren't turning more RPM or under boost!

The stock springs are good with that cam but are essentially the same as the spring in a ball point pen. Otherwise, you do have a good base motor right now. You can easily do new heads or a cam later.
You can have the ecu reflashed and increase the rpm and fuel pressure. Whipple has a stock program for Raylars cam. No need to increase fuel pressure. But again, I wouldnt with those springs. Your set up right now is basically a tank if you leave it alone. If you can live with yourself! LOL
