The block turned out to be quite nice. Decks are very straight may need machining just a couple hundredth's or so - talking in mm that means just a couple thousandth's in inches. Turned out that the deck height was 9.025" at my reference point at #1 cyl. | The block turned out to be quite nice.

− | + | One question was if to use aftermarket billet main caps and drill the engine block for a 4 bolt cap pattern or save that money for the next build. The answer to this is "NO", not at this time. The next build may include this modification but aiming at some 250 hp does not require such measures. | |
