David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting
I disagree with point 4, Vizard writes plenty of books explaining how he does things. Not like he's trying to hide knowledge, not AT ALL. As for porting 302 heads (or any heads), I have no illusions that I can pick up a grinder and match what any decent head porter can do. However, watching someone go through a set of heads and explaining what they're doing at least gives a starting point to anyone who's interested in learning how to port. Or is that supposed to be some secret reserved for some of the head porters who get so bent out of shape when other people post videos explaining how to do it? I'm not talking about UT, he is a hack... but DV is certainly no hack, and I kind of doubt AW is.
EDIT: this is in NO WAY directed at anyone in general and certainly not at kdeboy. It is my thoughts on exactly what I knew would happen. I’m not disparaging kdeboy, his knowledge, his talent or anything else. It just happened that he was the first one to articulate this position.
I just want to be clear on that. This is NOT a shot at you kdeboy. It’s my explanation of what the consequences of a build like this can and will be. I don’t want to see guys spend more money to make less horsepower. I absolutely HATE that.
So you think you can “grab a grinder” and match what a “decent” head Porter can do? Sorry but that’s just cRaZy talk.
Unless by decent you mean you can grind some metal off and not junk the head. Otherwise, there is a HUGE difference between what someone does with a grinder who actually gets paid to do the grinding and does the testing that goes with it.
You also exposed EXACTLY why I’m bitching about this cockamamie, idiotic build. It appears you are of the belief that with a grinder and some secret squirrel **** you can take a 302 casting and make it make power like a casting with a 340 port. THAT AIN’T HAPPENING.
There isn’t enough materiel in the 302 casting to make the ports the size of a 340 port head BEFORE you grind on the 340 head.
And that’s EXACTLY what I’ve been saying. Who in the world wants to do what Servideo got smoked into? Who wants to put 40, 50, 60 hours in grinding, testing, studying the data, thinking, more grinding, more testing and for what?
In the end you could have started with the better casting, done a nice valve job and do maybe, MAYBE a few hours with a grinder to fluff and buff a few things and you’d be far, FAR better off doing that than slaving over those garbage 302 castings.
Again, that’s nucking futs. And that’s my point. Why are they wasting time with 302 castings and port work? We all KNOW that you can’t hardly give away 1.88 valve 340/360 castings. No one wants them because by the time you install new guides, hard seats if they need them, cut the guides for seals and all that you can get a set of SpeedMaster heads.
There is no magic in standing behind a grinder for HOURS and HOURS and then repeatedly going to the flow bench to test. It’s not only physically idiotic it’s mental masturbation.
Again, this has been my point from the jump. Starting with a 302 casting is stupid and it does a disservice to anyone who may want to copy all or part of this build.
They didn’t save any money with the 302 castings. In fact, they wasted money and time all to make LESS horsepower.
