76' international scout conversion to tbi

[dave w]

Substantial mountain snow and below 0 temps have dampened my forward momentum here. Junk yards are no place to be with this kind of cold! I continue to "play" with tunerpro and feel like i'm making some progress. I see i was upgraded to Electronic Ignition! Progress man, one foot in front of the other. Any thoughts on this adapter for the 2 bbl international?

I've designed several TBI adapters. Sample IH 4 barrel design screen shots below. There could be a trade off in TBI adapter design, some adapter designs are focused on flow and other adapter designs are focused on low cost and / or "one size fits all". Sometimes it can be challenging to design an adapter to provide both optimal flow performance and low cost.

Gradcad has time saving downloadable CAD for the "do it yourself" designers: https://grabcad.com/library?sort=mos...ed&tags=holley

Attached is a drawing for the IH four barrel carburetor / TBI throttle body.

Have you fabricated or had this 2barrel design fabricated? Any feedback on how it worked out? I have machinist buddies who still have access to cnc machine tools and would probably be willing to fab your design for minimal cost. Do you or anyone you know have one of these for sale?

I can design a 2BBL adapter based on the drawing attached in post #25.

The inserted image in this post is an incomplete design that tappers / drafts the 50mm 454 Throttle Body down to 40mm bores on the IH 2BBL intake.

If your interested in knowing more about the design, please send me Private Message (PM).

Once again it's snowing in the mountains of new mexico. I sent a pm on most of this dialog, I just wanted to post some of it here for the sake of continuing this thread for anyone who might be interested in this project. I went to the wrecking yard and found a 95' chevy 1500 pick up with most of what i was looking for. Got the 16197427, throttle body, distributor, fuel lines, air cleaner, harness and associated sensors. I'm thinking you make a good point on using a fresh harness, the junk yard harness is questionable at best. The computer i got says it has BJYL. The donor pick up had the 4l60E. I downloaded the BJLH bin file you recomended, I still plan on using it unless you recommend going with a BJYL file.

1995 is a UNIQUE ONE YEAR ONLY 4L60E, that uses Pulse Width Modulation (PWM) Torque Converter. BJLH is for a 1994 Pickup. It's personal choice which .bin file to start with, but I would personally select BJLH to start with.
