4.0L HO Jeep Engine Build
Here I started to do some porting. Don't jump on me! It's not done, lol. The ports are just roughed in at this point. :) Note the cutout at the upper corners of the intake ports, that's where the injector sprays in from the intake manifold. Also note the serious core shift. I took a lot of meat out and the parting line is still there. I concentrated my efforts on the port roof and when doing home porting I try to "Be the air/fuel molecule" and imagine where I would want to go and pretty much stay away from the port floor. I don't have a flow bench so I do my best. If I were totally serious about this, I'd have DC do it for me.
