I have been using short runner header with my 6 litter M119 Motor with stand alone ECU/ Motec M800 and 722.6 5speed trans conversion.
I do not have any necessity to changed current setting for daily driving and some strip trial.
hence I am building new motor with solid tappet and billet camshaft, I shall try to make new header that I long time studied.
It would be 180 degree marge, i.e Cross bank. 1-4, 2-3,5-8, 6-7 180 degree marge as 1st φ48.6 inconel 1,0mm rolled pipe,
2nd is 1-4(R) with 6-7(L) and 5-8 (L) with 2-3(L) after trans, around drive shaft center bearing area 2nd φ60.5 also Inconel 1.0mm rolled pipe.
3rd is scratching but around φ80 around, 4th would be depend on road clearance.
I realized that we need 4 or 8 O2 sensor for sequential injector control with 180 degree marge / cross plane crank : )
Speed Niibe
