There are guys that sell 598 short decks with a warranty now. In the beginning there was no warranty as the development progressed builders started offering a warranty.

Thanks John |

Ok here's my 2 options I would like to pursue.
Option 1) 9.8 deck, 4.25 stroke, 4.590 bore = 562 ci Option 2) 9.8 deck, 4.375 stroke, 4,590 bore = 579 ci I would have to agree that option "1" would be the best for long jevity etc however if option "2" is proven without any real known issues then I'd like to go that route. I ultimately would like to achieve 775 hp plus or minus at 5,800 |

This a 572 then? Also does he have any time on it yet? I'd really like to keep in the loop on this.
Thanks John |

It's got a hydraulic roller in it. Somewhere in the 250/260 range. Only dyno time so far. It has the Profiler Sniper heads. The builder said the circle track guys are doing this a lot now. I dont know if I believe ot yet. I'm curious to see how well it lasts.
