Dusty Posted December 3, 2017 Share Posted December 3, 2017 So been working on porting n42 for my l28 build. Valves are stock size rebello intake valve factory exhaust. Test depression 28" water. Not much material removed from runner mostly bowl, seat, and chamber work. Was just wondering how these compare to anyone that feels like sharing.

madkaw Posted December 3, 2017 Share Posted December 3, 2017 Probably should state stuff like bore size, cam, etc... Quote Link to comment Share on other sites More sharing options...
Dusty Posted December 3, 2017 Author Share Posted December 3, 2017 Bore is 88.5mm. Cr is intended to be around 10.5 but head is at welder getting chamber closed up wont really know where it will end up till after its straightened back out and milled flat. Undecided on intended use either hot na or possibly turbo Quote Link to comment Share on other sites More sharing options...
