didnt want to jump timk's thread, well I dyno'd a whopping 231hp/280trq. all with a bad overheating problem and 7cyl. (n2o backfire a while ago lifted a ring land and did not know it until I had head work while I fixed what I thought was a bad head gasket). The tuner came out to me and was like "what is your timing at, this thing is pinging its a$$ off", thats when I told him the problems I have with the short block. Not bad though I was hoping to get 220 with it the way it runs right now. My a/f was 11.4-12.4 so a bit rich but I feared I might be lean (did not know if I was lean and that was also contributing to a overheating prob.)
