Thats exactly where this one is headed. Lmao. But if above 102 kills them I won't explore that option. Thank you.
I ported my 7900 and picked up roughly 12% on timed cuts in a 12" oak cant log. I ended up at 101 on the exhaust, 130 on the transfers and 80.5 on the intake but I also used a 460 piston with an aluminum base gasket/ spacer. It runs a 28" bar with an 8 pin sprocket and full comp chain really well. I am planning to raise the exhaust a little more and to replace the coil with an unlimited unit. Then I will do a build thread with a comparison to a stock 7900 with the slab sided piston
