    70 Z28 Choke stove looks like this, and I assume 71 is the same.

    I had assumed the opposite Mark. A '70 has a "well" in the pad into which the bi-metal coil hangs . . . Just as for '60s cars. In '71 the pad is flat not recessed and from the looks of this one the bi-metal coil looks to sit higher than the one in your photo.

    Mark, group 3.750 PN 3887148 good for '67-70 Z/28 . . . PN 3989061 good for '71 Z . . . GM catalog for Camaro dated Dec '71. Would suggest they are different parts . . . Visual would tell for sure.

    GM was pretty crazy back then not leaving things alone that worked.

    It is a puzzle . . . Maybe GM knew something we don't. But it does seem odd to go through the design change process on something that, on the surface, seems pretty much the same.

    Copo, Thanks for the info but my stove is flat not dug out making the open coil not correct because it will bind the springs once fastened down. I'm looking for the correct 4801 Holley for my 71 Z28 and in my search speaking to many different knowledgeable people I also discussed that choke stove and I was told that the stove was different on the 71 Z28. The spring on this manifold where the rod hooks to it I believe that it should be on the 9 o'clock position not 2 or 3 as shown, but not 100%. Thanks, Bob

    Modified original post. Choke thermostat is no longer included with intake.

    My friend is open to offers so don/t be shy. worst he can do is say no.
