Are you changing or upgrading your cam and valve train during your rebuild? If so, what are you planning on going with? I have a 26' Eagle with a HP500EFI and will be following your rebuild closely, thanks, Larry.
Yes, I am. Valves do to 2.25 intake and 1.90 exhaust. The cam also get bumped up, not sure to what as I bought this package (http://www.crockettmarineengines.com/products.html) from Crockett. He claims that this package will net +/- 515 hp out of a stock 502 short block. I am bumping the compression up a little more than the 9.0 that these numbers are based on as well as going to 509 ci. So who knows, I may be in the 530-540 hp range when all said and done. I haven't decided if I am going to dyno it or not yet, so I may never know what the final numbers are.
