well, spent the last week or so trying plus one valve heads, and new cams on the 800. Carbs, intake, exhaust all the same as last year.. sucks as I messed up a valve on the plus one valve heads and had to go to a ported set of stock valve heads... anyway, here are the charts.

made one or two nitrous pulls too.. sucks I forgot I was out of propaine so no way to heat the bottle up to normal temp. This run was at 750psi or so... in my testing I have found the difference between this, and say 1000 -1100 psi is at least 10 hp more... I expect this to make 125+ with a warm bottle.

I forgot to mention, I have two different sets of bigger carbs to try. I think the 38's are to small. I was hoping to be around 80- 82 on motor with the big valve heads and bigger carbs....

Yeah, it is not bad for what it is. I just wanted to see what it would gain with some "real" heads and better cams.... if it makes 130 or so with the big valve heads I will be pumped.. 85 ft lbs of tq should be a good time.. LOL
