And exhaust manifolds , front of engine stuff may change etc. 354 Block is the same ; ---if serious , Hot Heads aluminum hemi heads and intake is the way to go on this idea. Rebalance needed too. Lots of $. Same steel crank Also true of 57-58 Dodge 325 poly and dodge, raised Red Ram block / hemi heads (56-57 315/325) However , power pack 325 4 bbl poly is only about 15 HP down on a hemi D500 ; not worth all that work . What is HP of 354 Windsor poly with 4 bbl? Probably not bad. Surprises people Interesting on that, Dodge changed the lifter angles between 241/270 low block hemi and 315/325 raised block mini hemi , (made both correct, thank you Burt) making identical appearing Dodge V8 cams or cam cores not interchange at all (big pit there if you did not know that..I did not!) . But Chrysler apparently did not change lifter angles?? To 392? . . I wanted to talk to Burt about that, but time flew by. The legacy of that, which he passively agreed to, smiling, was the 273/318 /360 has poor pushrod angles all the way through production (tooling originally designed for a Hemi or Poly rocker tip location, which is closer to center of bores) ..must have used the same , then new, tooling. Chrysler came up with the special R block to fix that, 20+ years later? which then required a special camshaft. Somehow it all ties together… From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of dverity@xxxxxxxxxxx [Chrysler300] I would think you would at least need Hemi pistons, and push rods. Don Sent: Thursday, August 16, 2018 12:04 PM Subject: [Chrysler300] regular 354 Windsor block to a HEMI??? I have been told, mainly by folks on the F/L site, that a regular 354 block such as would be found in a 57 Windsor, can Be converted into a Hemi simply by installing hemi heads. Forgive my stupidity here, but why am I just now hearing about this and is it true. What all is involved?? Sounds WAY to simple and easy to be true. What am I missing here if anything??
