Propane or CNG Head on a 5.9 Cummins February 09, 2009 01:14AM
Does anyone know or have experience with the Cummins B5.9G head? Looking for a sparkplug motor for a lite limited alky tractor. We arent allowed to convert a diesel head over to sparkplugs. We run a 3 by 4 turbo and a 360 inch limit for alky tractors. Would a B5.9G be a good choice or should I look at a different motor? I don't really care about brand cause I can find any rearend. Thanks!!!!!!!!!!
