FOR SALE 300K powertrain

Geff McCarthy · Jul 13, 2025

Numbers matching 64 300K motor and 727, with correct single carb. Plus, long sonic ram tubes for 62-63, and 284 Street Hemi camshaft. Motor disassembled, transmission assembled. Located PDX, might deliver San Jose to Vancouver BC. $5000. Will not split. More photos when I find them. A few serial numbers:
Block 2205697 4 bbl manifold 4100340-1 heads 2129985,7 sonic rams 1947162,3 all correct for K.

I think the photo of the exhaust manifolds is not for the K. I do have the correct K exhaust manifolds, one is split, but weldable, as the separation point does not impinge on the port.

Do you have a photo of the correct manifolds with casting numbers? You block photo leaves a lot to be desired.

Your intake # is not correct as listed. Your picture shows intake # starting 220...., which would be right for '62-'65 413 or 426W.
Exhaust manifolds are later '67-'69 383, 440 Magnum.
