Has anyone successfully used a throttle body with the GM/Chevy 292?

I don't know anyone personally, but I think it's do-able. I think there's a system for the Jeep 258 L6, that should have a lot in common with Chevy L6s. A throttle body shaped like a squarebore 4 bbl would fit on a Clifford or Offenhauser intake.
There is a special forum called ''Blown and Injected'' on the Inliners International website: www.inliners.org that is specific to this topic. The hot running thread is about a Pontiac OHC 250, which has a different head than the Chevy 230/250 L6s. Also -- sadly-- his photos have disappeared -- it's a long running [five year old] thread.
I run an Edelbrock 1404, 500 CFM 4 Bbl, w/Offy 5416 and Clifford headers on the 292 in my '68 Chevy C/10 stepside. Fuel injection on a later project interests me.

It would not be difficult to machine an adapter to go from the square shaped inlet of the Clifford or Offenhauser intake and allow the standard Holly 2 or 3 bolt throttle body to sit on top.
Will check out the Inliners International website: www.inliners.org for more info.
Thanks

On a different question, found a number of references to GM/Chevy 292 dual cast iron headers, but all the sources I found were sold out.
Are these dual cast iron headers easy to locate and are they worth the money?

I think the cast iron headers you're referring to were the Langdon Cast Iron Headers. They were a more modern version of the old Fenton headers made for early Chevy L6s, like the 261 and 235, and the GMC 270 and 302 L6s [not the V6s]. Tom Langdon, a retired GM prototype engineer, ran the Stovebolt Engine Company which sold those headers and a lot of other GM L6 stuff. Tom Langdon retired completely last year, and sold the business to Tom Lowe of www.12Bolt.com. Mr Lowe may or may no longer have the Langdon headers. [EDIT: I checked out the site; he lists them, but is currently sold out.]

Tom Lowe would be an excellent source to ask your earlier FI questions. He's also into turbocharging these L6s.

The FiTech Go Street EFI 400 - $795.00
will work with you 292. You can use Offenhauser Single-Quad Intake Manifolds 5416-LK. I have seen VW Bugs using the 600hp version of the 400.
