Thank you laynlo very helpful. So maybe I order 1 and see?

So I blew out the front seal and did a blow down test. All cylinders were at 5% except 2 is at 22% and I hear feel it blowing air up through the oil air separator, so that means its going by the rings into the crankcase. Im guessing got a broke ring land. Got the head off that side. Bore and even top of piston looks good. Should have piston out tomorrow.

If it is I will post up pics. So Im gonna forge it while its down.

Question should I go 10 to one like the lt4? It should be more forgiving an easier to tune I suppose but at what power cost with 12 pds of boost

this is at 660 rw
