Just wondering as me an nitroused383 were trying to figure out how much power you and another member who ran 7.5 at a lot less boost are getting the times your getting, and it's easy to see you were out the throttle now and other issues were keeping you from running to it's full potential. Makes sense now, good luck getting everything going full throttle!

well...failure diagnosis is in...
Shortblock looks good. Going to get at least new rings and bearings. Heads are JUNK.
Looks like COP is coming off the car and going with a dizzy. We think timing jumped at some point. straps on plugs 3, 5, and 7 were burnt.
Crack in passenger head (across the plug holes)

On the other hand we were chatting with Shawn during the live feed and he mentioned something about the shape of your intake port on the heads, being what was causing some of the spooling problems, I guess now you have an excuse to go to some nice rectangle port heads!

Ouch that hurts Brian when I got the text about the heads being cracked I was like WTF. Seeing the pictures makes it look 10 times worse than I pictured in my head.
Makes my junk lifter I found tonight pulling my heads to inspect for a blow head gasket look like nothing.
I am sure it will come out even more badass in the spring

well....I'm not constrained by anything at this point. MOZES is out since it takes WAY too much to make those happen in the lifter department. Doubt I'll stay cathedral anymore.
