Is there such a thing?
I am looking for an 'elbow' that has
a (Holley) carb mount , on one end, and,
a (GM preferred) throtte body mount, one the other.
Does not have to be for GMs. Prefer low riser.

 

Accel part #74882.

They call it a "Plenum Adapter". It's probably pretty pricey.

 

Do you mean an adapter to fit a TBI to a carbed intake?

If so I have a brand new Holley one that I'd be willing to let go of.

PM me if interested

 

Holley (and Edelbrock ?) offer a mpfi version of their
single plane manifold.
I'd like to know all the options for putting
a throttle body, w/ air intake hose, on those manifolds.
What I've seen so far, looks like
first day at welding school.

 

Accel also offers a MPFI single plane intake manifold. It's known as the "Pro Ram". You can get a pre-built fuel rail assembly for it as well. The Accel plenum adapter is exactly what you're looking for. It simply bolts to the carb flange and allows fitment of a TPI throttle body at the other end. It's basically a 90* elbow with the proper mounting points at either end. Hood clearance would really suck though, lol.

 

OK, so does Accel have a website?
(not their 'vendors')
