That seems like a pretty cool software package, is it expensive

Not really. I have prob around 300-400 invested in these software programs.

The latest camshaft software , can really demonstate head velocity characteristics, by adjusting valve size, throat size, valve lift, etc.

Sure seems like you'll have a fun reliable boat. Nice looking also. Appears you have all your ducks in a row. Just keep an eye for any reversion.

Was hoping to post some dyno results by now but had a little scare Monday morning. They called me and said 3 holes had 0 compression and 5 had 160 lbs. Not the best way to start off your Monday morning. So finally yesterday I found out 3 of the lifters were pumped up or something and were keeping the valves open. I have been cringing at what I had done wrong or I had bent valves for some reason. I probably turned this engine over by hand a few dozen times just checking things. The lifters were the Howards 91162 which I believe are the Morels just re-branded? These are the .750 roller hydraulic race version. Now I have never ran a hydraulic cam has anyone ever had this happen before? I live in Sparks with a Summit so my wife was able to go and exchange them for a brand new set as the motor is on the dyno. That was a positive.
