Design a custom cam for me thread
I found an hour and a half tonight. I got it down to where I just have to pull the balancer and the timing cover. I am not sure when I will have time to get back after it. Perhaps an hour tomorrow night or sunday night.

Everyone is dying of anticipation.
I would have gone with a 360/360 duration cam so that the valves are always open so they wouldn't make noise. Plus you get as much rev capability as a rotary.

The idle is a nice improvement. It has a little thump now. Although, I might like even more. The valve train noise is less, but still there.
I went down to the 1/8 mile at Sunshine Drag strip tonight to Run 7.50 index. The car went a 7.39 @ 94.29 in 1000 D/A. The car was on a 7.37 pass in eliminations, but I had to get on on brakes.
It appears to be about a half a tenth quicker with the same MPH in the 1/8 in 1000 D/A than it was with the old cam in 700 D/A and a tail wind. It actually picked up 2 hundredths in the 60' over the old smaller cam which was very surprising. Tells me that I could have went bigger on the intake duration. I may retard the cam 1 or 2 degrees to see if it picks up some more MPH.
It also leaned the car out about a half of a point. It is at about 13.2 right now. So I will jet it up 1 all around and see if this cam likes any more timing on Wednesday night. We are forecasted to have better air on Wednesday.
