Looking at the photo with the board across it, it looks like you will need to drop the carb way more than is possible even with a low intake, if you want to clear the hood.
So, if you do not want/can't do a hole, or no hood at all, you may want to consider a "Power Bulge" in order to clear an air-cleaner.thumbs upcool smiley

The Holley intake, with a QJet carb, allows just enough room for a 10 x 2 inch tall air cleaner on my LM.
I measured and have the crank pulley at the same pozition as the stock 'vair engine.
The cast iron imtake in your pictures is very tall and heavy.
I happened to run across the Holley intake at a swap meet for $75.

Here's a few pictures of the mock up of the motor mount we are going to be using. There will be bushings between the sections

I used a crossmember that goes under the oil pan and uses the stock side mounts.

I used a mounting system similar to what you pictured on my V8 back in 1971.
I didn't like the long span from the trans to the rear crossmember so that is why I wantedent with the under engine crossmember.

If you want a fuel pump with return line I'm using one from an '85 Astro van.

I'm going with the stock 6 had that span, should work here too. It might be more stress then the adapter wants though. I think we're going to look for a pump with out the return. Thanks for the offer

Aw, it would look so cool with some cross-ram tube to a pair of webers!

I used the Eldelbrock 2111 intake and a spread bore adapter so I could use the factory Q-jet carb. Had to use a cast aluminum carb hat with a hose and remote air cleaner to get hood clearance. It looks good with this set up.

So - A 4.3L V6 - Are you feeling really adventurous? Or just a little?

That 6 pot injection sure has the visual impact factor! Not the way we're going though. Has that Holley intake been ported for larger heads? I see welds above the port area.

I had it ported to match the Aluminum GM Bowtie heads (2.02" intake valves). A little extra material added to provide enough gasket surface. I have an Edelbrock manifold that I had matched as well. Choice of Carb/TBI on the Edelbrock or Port injection on the Holley Manifold. Are you using an 85-91 Corvette Water Pump?

I think that was the pump we ordered. rev rotation, short and aluminum. I'm still sorting out what intake to run. I'm trying to find the shortest for hood clearance. I'm getting the steel bent for the mounts and a hub/adapter getting done at a machine shop.
I'm considering building strut rod like what is found on 4X4s from the side mount pads to the bellhousing.

I wonder how tall the Edelbrock manifold is? Those individual throttle bodies sure are nice!

Don't forget the alternator fan has to be non directional or for reversed rotation.

Looks like the Edelbrocks are 3.84" for both the 2111 and the 2114 manifolds.
The marine one i have found, the seller said that it was about 4"

I'm still trying to find info on the Holley GR-15, Then I might need to find a used one.
As far as the alternator, so far we have the Vair Generator pulley and fan mounted on the 120?SI Delco

I went back to work this year so I'm back to working on the Vair on weekends. So, here's some progress.
Had to cut the pan down 1 1/2 inches and use a 5.7 pump pick up to match, hacked up some tube type manifolds and used some U bends for the exhaust.
I did get the cardboard engine mounts bent in steel.
And have the new radiator mounted in.
I'm still in the trial stage on the fitting of things

Which application are the exhaust "manifolds" Astro Van? A couple of move views of the rear mount would be nice. 6" balancer? Which starter will you use, the original Corvair or a reversed V6 one? Depends a little on the clutch/flywheel used. Looking good.

Seth, the manifolds started as 85 C20 pick up units mixed with an 87? Gran Prix set. I have some build pix of them and Ill see about the mount pix as well.
We will try to use the Corvair starter,it's an aftertmarket hitorque one. I think it should work with the torque converter

Got some work done on the 'Vair this last week.
Rebuild the tail lights
Did some engine bay wiring
Mounted the trans/engine oil cooler and fan
We did get the trans adaptor back from having the starter bulge and the filler plate welded in

Waiting for the trans to get back from being rebuilt.

Hoping to hit it hard when the trans gets back
I'm getting kinda anxious to have my shop back
