ah, got it. yeah, if I could still return this unit and get something else, I'd definitely be looking into it. As it is, I'm $2k in the hole on this, so I gotta make it work.
That zr2 belongs to @blazenwhipDo you know modifications were made to the ZR2?
I'm not sure what you're asking.
Yeah... I took the night off in order to come to grips with how much work this is going to be.
I'll start pulling stuff apart after work tonight.
Just curious, seems to be mostly stock other than the larger tires and flares, and handling the trails very good.That zr2 belongs to @blazenwhip
Don’t see him on here too much anymore, but he’s a good dude
Mostly it's the hard lines coming out of the back of the air box. There is plenty of room for the air box to move to the left, but then I would need to have the hard lines redesigned, and the brackets rebuilt. It's all "doable", but in the end every option brought the suck. I decided that the least painful option was to redo the part that I knew I had the tools for.Ash, what blocks you from moving it left and away from the cage bar? Is it an interference with the cowl? firewall hump for transmission ?

It seems to be a nice unit.Nice final result, Josh.
Makes me happy to see a sucessful VintageAir setup in a 1st Gen.

Blows good and strong but the blower is a little louder than I had hoped. No outside air intake might be part of that. Also, no floor vents. Probably not a big deal, but I was surprised.
I wonder if it's just a quirk of the 67-72 body style and where they have the unit installed. It is pushed as far to the PS as possible. It does seem like it would have been simple enough to just run another vent line.My restomod air has floor vents. The vintage air units I have installed all had them also.
I need to run it more to see exactly where the noise is coming from. It is the squirrel cage, but I wasn't able to check if it's intake noise, or the fan motor itself.LOL....
Intake noise through the squirrel cage or is it just the velocity of air coming out of the the vents themselves?
When you have nothing better to do, you could play around with an intake / muffler on that intake fan to attenuate the noise if that's where it's from.
I bought a "mock up" Gen-IV unit from VintageAir (still in the box) so that I could play around with the firewall mount as my firewall is built/rebuilt. Would love to mount it higher than stock (if possible) but from what I can see in your photos the limiting factor is the lower cowl where the rainwater collects?

Looks like #751170What part number was your kit?
@ktmoutfront You got me thinking, so I called Vintage Air and it does actually have floor vents. He said they are on the firewall side of the main unit, so I just didn't see them with the unit installed. Since I am using the stock controls (with their cable converters) it wasn't obvious to me where to put the slider for floor vents. When I get a second, I'll go out and play with it.
