69 Dart GT Conv. 340-6pak
Well in my never ending quest to fit a six pack under a flat hood, the next paragraph has been written. After milling .500" of the mounting bosses of the intake, and got the hood clearance I needed,I ran into another issue, the stainless top radiator hose I built was now touching the front carb. Since all Chrysler water necks for the 340 are straight up, I started looking at what I would need to lower the top hose away from the front carb. After looking at several, I landed on the early chevy (55-57) water neck. This neck will not accommodate the oem size thermostat that I'm using, so I started designing a 45 degree angled water neck for the small block. Using the chrysler o-ringed base measurements and the chevy top measurements, I had a Baker Machine mill 2 pieces out of aluminum and we tig welded them together. I then ground and sanded the entire housing starting with 40 grit all the way to 400 grit, then buffed it. Some 6 hrs later I have a 45 degree, O-ringed water neck. I put it on today and all fits great. Now its on to remaking the housing end of the hose to fit the 45 degree neck, and don't think it will be too big of a deal. Wish me luck.
