Chokes and headers...

[mungus]

So what are most folks doing about the factory hot air choke systems when they fit headers?

- No choke? (not ideal where I live I'm afraid, winter gets wet and cool)
- Manual conversion?
- Electric conversion?
- MiG some tubing onto a header tube to feed the OEM hot air choke system?

Interested to see what everything thinks and does.

As part of this build I'm fitting a list 4609 730 CFM Holley 4150 and have a set of lovely FPA headers.
And to be honest I'd rather not weld them as they have been cerakoted.
Both the 730 CFM carb and my OEM 600 CFM have the hot air choke system fitted.
I'm thinking the simplest and cleanest set up is a Holley manual choke conversion kit.
I think Bill at Mansfield's even sells the OEM manual choke conversion kit cable...

I shaped and clamped a tube to the headers on my small block.  I think the actual choke tube setup came from Pony Carbs when I had my Autolite rebuilt, but they are long gone so you will have to improvise.  Works fine.

just run the hot air intake tube around or along a header tube , easy as it gets

In Jim's picture you can see the end is not crimped because it needs to breath. The vacuum sucks in the hot air. You may want to flatten it or partial plug to keep mud dobbers out. Steel worked better for me than aluminum.

OK, so are most staying with the OEM hot air system?
Seems you can do a reasonably tidy job pipe wise anyway.
I dud see someone selling complete hose kits just recently, maybe Mansfields?
