I think you've got the right idea of where to mount the reservoir in the engine bay. I assume the top of the windshield wiper fluid bottle is as high as you can go, otherwise you could just add spacers to your mount to raise it up. I wonder if you could relocate the windshield wiper fluid bottle inlet so you could rotate the reservoir so it could straight shot and then onto a 90* fitting to the pump. It might be easier to relocate that then the reservoir itself. Just a couple thoughts.
The build is looking awesome btw. I would personally go with the stock hood incase it gets banged up from a tree. You can't knock back fiberglass. Just my opinion.
I don't know how durable the fiberglass is or not but I can also swap hoods anytime. With all the dents and dings I've had in my rig I've never touched the hood.
If there’s not much real performance advantage, I’d go with the fiberglass hood. It’s lighter. I’d also leave it as is with no vents. The grill, radiator, and fan will keep that bad boy cool!
You're not trying to cool it more you're trying to get some of the heat that is produced by that larger engine out from under the hood.. The vents aren't made to help the radiator cool the engine better but to help remove the heat.
The straighter and more vertical that connection the better. Hard to tell from the pics, but it looks like that could work If you can complete the connection.
You may recall, on mine I built a bracket to mount the reservoir to the front of the head directly above the pump. It created a very short connection to the pump, but didn’t have to worry about flex on that hose since it was mounted, and moves, with the engine.
I looked at the front of the engine for a spot to mount it but from what I remember it would make it too high. But I will go back and relook at it and verify.
