The Binderplanet is an IH-Cornbinder site. The injection forum covers installing the GM TBI system on just about any engine made.
I'm not familiar with the Holley 1 barrel projection but have had a lot of experience trying to get the Holley projections working properly. I sold them just like the other guys on ebay and went with all GM factory TBI parts.
They work right and last a long time.

The IH inline 6 is almost identical to the GM.
Infact Almost all 1 bbl 4/6/8 manifolds have either the standard small or large bolt and bore pattern so they all interchange. I have developed the adapters for both to use a 2bbl throttle body and I also have a 1bbl adapter to use the GM 2.5/3.1 1bbl TBI on the inlines.

The delco distr used has already been discussed and I have a complete write posted there that Kevin used to modify his for this project.

There is no reall engine or brand specific application. the system doesn't care what engine it is bolted on and it doesn't know. It's all in the chip tuning once it's installed that makes the difference.

So forget about whatmake of vehicle we may be discussing and just apply the information to yours.

Here is a direct link to the EFI FAQ's-frequently asked questions.
It covers every thing by topic from the wiring to the parts required to the distr conversions and there's even a junkyard shopping list you can print out and take with you.
