lean burn
Just as easy to go to a nice running 1406 Edelbrock 4 barrel with the electric choke.
Can use the Mr. Gasket 2 to 4 barrel adapter (20 bucks at your local Advanceautoparts store) on your lean burn manifold.
Also works on the '89 - '91 TBI intake manifolds too, need to redrill the 4 mount bolts to keep it on center.
