Ive read a few times something about a Mopar bible, somewhere within this bible is some sort of stencils for do it yourself home porting, Indy told me they do it for another few hundred, Im sure that they would do a MUCH better job than I could cause they have the experience but I told him no cause I want to do as much as I can myself, Ive only built one other V-8 motor myself and that was at least 15 years ago, it was a 340 and that thing was unbelievable. Sounded great, ran great ect. Only mistake with that engine I made was putting into a big heavy ramcharger.
