Is my Bonneville 389 worth anything?


New member
Hi all. I have 67 GTO project that came with a salvage yard 389 out of a '64 Bonneville (per the previous owner). It needs a complete rebuild but isn't frozen. Everything is there including the headers, distributor, and Carter AFB 4bbl. The engine code is 28P, casting #9773155, date code D274, and the intake manifold # is 18438572. I don't need this motor because I'm planning to go with a crate motor. Does it have any value? Thanks for any help.

It definatly has some Value, any 389 or 400 Pontiac blocks are starting to become hard to come by. It biggest Minus is it is a pre 1965 block, and is limited in after market parts by the different bolt patterns used on those. But I would definatly try to sell it, you may be surprised. But you should be able to get at least $500 for it as it sits. Probably more.

where are you located? That actually makes a big difference in value as shipping costs are prohibative.
