Built my own using an old 650 DP. Hanger18fab is what I used as a baseline but I did a few things not mentioned to mine that have helped alot. If you are interested I can explain.

The biggest gain I got in the tunability was making vent tube extensions. All this is, is 5/16'' steel brake line that gets epoxied into the vent tube holes and extends all the way into the carb hat and ends at the hat opening. Be sure to flare the ends. What this does is it fools the small jetting into thinking they are bigger jets, this allows small jets for better drivability and when you start making boost at higher rpms the tubes get the ''ram air'' effect and will pressurize the fuel bowls thus pushing more fuel thru the small jets. I dont street drive the car at all but this helps me not foul plugs and allows me to get up on the brake without any fuss. This is the only picture I have of it.

Another problem I had was I pulled the threads out of the air cleaner stud hole in the carbs main body. This is usually a 1/4-20 threaded hole and turned out to not be enough. I drilled and tapped it to accept a 5/16'' stud which should be sufficient. I then had a problem of blowing out base plate gaskets so thats when I made the ''Hat Brace'', its ugly but it has cured all my issues.

Is that a football?
It sure is. I was looking to save a buck so instead of buying an airbag for the right rear coil I picked up a football from walmart, deflated it and stuffed it in there and inflated it to 8 psi. It does an awesome job of keeping the car from torquing over too much in the first 60'.

That's creative. Nice work, haha. I can always appreciate it when guys get it done with what they've got instead of buying all the best of the best.

Over the winter I do plan to put in an anti roll bar and some adj uppers. I might even spring for some 90/10s up front with some 175# springs in the stock K-member.

Last I heard he was building a front engine dragster. Twin turbo of course. It's been a while though.
