Holly tbi 2.5
« on: November 25, 2020, 06:50:17 pm »
I’ve got a line on the fabled Holley TBI. I got someone to make the adapter. Is it worth the $400?

Never mind. I just bought it for $325... I hope I didn’t make a mistake.

I think the Holly TBI only fits the 84-86 duke. It got a new throttle body and injector in 87, along with DIS

This is what I found. Looks like I need to build a plate.

It would be interesting to find out what they did to the intake manifold.  Maybe that could be duplicated on your (spare) manifold.

If someone has a spare 87-88 manifold that I could play with I’d be greatly appreciative.

Have not picked up the new motor yet so no spare yet.

Here is the Holley manifold.

I’d appreciate that. I could give you mine once I’m done. I think I can make the adapter myself but 😱
