Slingshot [or other dual] meausrements, advice

[Talkwrench]

Still contemplating a dual setup on my 21 stud 37. And with only about two weeks before heading to California need to make a decision.
Is there someone that could "sling" me some height measurements of a slingshot setup so I can see if it will fit?
Im thinking the slingshot would be best, good as I would not have to move the Alt, however Im not sure if it has any provision for a vacuum outlet?

SO whats the go with vacuum on a dual? I will be fitting a vacuum booster for the brakes.

Heat risers?

Im open to other setups if someone has a good suggestion.

Cheers!

I have the slingshot on my car and love it. I was able to pull the vacuum for the dizzy from the intake itself. it also has another area near the rear to pull vacuum from. I'm at work so I don't have many pics or measurements. I did have this pic on my phone. If you look closely behind the water neck you will see a clear tube coming out of the intake and back into itself. This is how I blocked it and when I install wipers I will connect it correctly.

With dual 97 on a Harrell intake and a mild smith cam I have 17" of steady vacuum. The vacuum is on one of the intake paths. Hole is tapped for a hose fitting. I can get the duals and a reproduction Thickstun (low profile) air cleaner under my 34 hood. From the intake surface on the block to the mounting of the carbs. is 8-1/2" to the base of the air cleaner about 14" and to the top of the air cleaner 18-3/4" Don't forget you need a few more inches to get the air cleaner off for work on the Carbs.

Not sure which car you have, I just did this swap on my 37 21 stud in my Deuce roadster....everything fit nice !

If that's the sort of measurements Im Looking at I don't think it will work realistically I have 17" from the top of the block .. Also any vacuum ports need to be big enough to take a larger port for a 3/8" hose.
Deuce its a 35 pickup. Have you run that motor yet?

If I have to go the basic 2x2 super can you get an offset for the alt mounting on a 21 stud head? How do I get it out of the way?

Can someone give me an honest before and after?

I just measured from the block to the top of the acorn nut holding the air cleaner on and it's
16 1/2". That would give you 1/2" clearance. It also has 2 ports for vacuum, I'm using a 3/8 threaded port reduced to run 3/16 brake line for my dizzy

Also buy it through summit, they beat all prices, I got mine for $389 shipped. Sorry last pic was sideways, here's a pic of the vacuum port near the front

Thanks for that.. does the slingshot have any sort of heat riser in it. any problems with none?

Yes, the Edelbrock slingshot is heated.
