yeah, I know. the 260 cam is in their to match the 11:1 compression and I did make improvements in ET going that route. 2 tenths improvement. the next combo will obviously get a bigger cam to match the 13:1+ compression. ran a best of 10.35@130 and 10.39@131. this thread was started to just get some direction on next combo with this block. the results of the leak down test shows I can run this combo another season, but it will have huslers a vacuum pump and a davinci dominator and I may have sanchez take a look at the heads for the next combo though.
