LA 340 Intake Manifold

Yep, your engine sounds like a hot rod piece. Overbuilt for most street cruisin'. Pull it and sell it. Like mentioned, a Magnum is a goid choice.
Yeah it was a hot rod no doubt. It runs just not optimally of course and the converter is un matched. I hear ya about the Magnum swap. I also have the or318 but that needs to be gone through as well and may require machine work.

How does one find a decent magnum motor? Salvage yards suck here in phoenix. Do they furnish cherry pickers? I don’t have a truck or anyone to help me so thats a problem right there…
