Re: OT 354 poly

["Gary H." <62to65mopar@xxxxxxxxxxx>]

Yes. Not all polys convert though.  "Chrysler's 301, 331, and 354 polys and Dodge's 270, 315 and 325 polys can easily be converted to hemis by adding the proper heads, intake and exhaust manifolds. It is important to understand that polys can be converted to hemis only within an engine family. Chrysler polys accept Chrysler hemi heads, Dodge and early Plymouth polys will accept Dodge hemi heads. DeSoto never produced a poly head motor so DeSoto hemi heads won't work on anything but a DeSoto hemi. (The 325 ci. Firesweep Poly head motor installed in some 1957 DeSotos were actually Dodge motors built in the Dodge engine plant.)"

So the 318 Poly family of A engines had no Hemi motor based on it. So Hemi heads would not fit those polys.

Thanks,
