I have a complete running .030 over 425 HP (target) build out of my jet. Gil marine 10 qt pan, performer, Herbert .490 lift 230 duration hyd cam. Brand new Marine starter. Pulled because of an auto accident, not because of any engine issue - with an 850 DP and no cover spun my berk A to 5200 RPM. 850 DP not included.
I know it's not exactly what you are looking for so it may be more than what you are willing to spend, but PM me if interested.
I can start it as it sits and am willing to sell it less periferals (manifolds, water, alternator, etc).
