gentlemen, I did not flow the head and installed lumps and valves myself. I like to play with that sort of stuff, maybe an ego problem.I have a bhj dampner on it and it`s smooth all the way down the strip.The reason I put the monster carb on was I got my butt kicked by a car set up very similer to mine and (he said) he was running two 600 holleys. I did see it.The reason I was considering convertor change was I missed the shift by 400 rpm and hit the rev limiter on almost every pass. I haven`t done that in a long time.As soon as my grandkids empty my bank account this holiday, I`m going to make some of your suggested changes and take her out again. thanks
