Latest 2 barrel adapter

[Bill usn-1]

I have never been that happy with the adapters avail so I have been designing what I like and working with several machine shops to try and get my designs produced.

Here is the latest small block GM TBI to the IH 2 barrel manifold adapter.
This is the initial prototype but hoping to have this in production soon and included in my future TBI and MPFI kits.

I'm glad to see you are making an adapter Bill. They should be a good seller.

Hoping to get them into production soon.

I got my adapter and it looks great Bill, it lines up great with the stock manifold on my 304, I will post some pics when I get it all together

The available Holley adapter is for a BBC TBI, which most IHs don't need, so this fills a niche not currently served. It's also ~$110.

I'm running two of them, both with a small-block TBI on top, so some of the tapered port effort/impact/attempt is wasted running the small TBI on the big TBI holes.

How thick, and how much?

There already listed in the parts and service sticky.
$100 shipped with hardware and gaskets.

i run a small block throttle body on my stock 392 in my 72 travelall.
It has no problem hitting 100 map at WOT-wide open throttle. Which means it delivers plenty of air for the 392.
