That is some awesome info there, seems like an amazing program, i downloaded the free one, butits nothing liek that lol. Thanks for that, as far as the rod grinding goes, 4 were hittign the cam, so we took exactly the same amount of eachone, and accurately by with 1/4 - 1/2 gram. It was only the tiny corner on the rod, not much, so technically if u do a tad of each corner, i figure ill get some piece of mind that none will hit, and that it will be in a much closer balance than taking off just 4 rods. BTW, Im nervous about spray, but I wanan put myself a little higher, figuring 100-125 wet wound be perfect. The compression ring gap is set at 25 thousanths now, an well experienced machinest said to do that becuase the number one reason for failure of hyperuatics is that the piston expands more than forged or cast, and a lot of people are getting cracked pistons especially with spray. At least that is the drift i got from it, he recomded 24-26, so 25 was the median and the winner. This is a common driver, more than a wekend warrior, so i wanna be safe, but if done right, retarted timing, not running lean, and with a wot switch I think I will be ok, at least I hope son, any other opinions on the spray, im pretty happy with the natural power will be. BTW i didnt get forged because I got an awesome deal on the whole rotating assembly because it was discontinued with the hypeuratics, so summit dropped it down to like 750 with a steel crank, forged rods, and the silvolites. Its been a bumpy build but I hope it all works well. Also, If I do use a plate style nitrous system, the 3/4" or 1" thick plate will serve as a carb spacer all the time correct? The base build I mirrored used a 1 inch open spacer, so who knows. Thanks guys.
