So I was planning on doing a 6.7 Cummins build but life had other plans..I picked up a pretty much complete 12v out of a 97 missing the pump,gear,and cover..for 200 bucks..I'd like to build a p pump 24v..will a 24v head bolt up?? What will I need to make this happen..12v and 24v blocks the same?? Any help would be appreciated..
