Re: [Chrysler300] 4006452 heads on a 383 engine

[" Mark Lindahl" <mplindahl@xxxxxxxxxxxxx>]

Hi Jim and All,

Russ Vaughan to the rescue.  As usual.  The original 383 push rods will work with the original lifters.
Russ told me that I could not use the original rocker arm assembly due to the built-in spacer that is part of the assy.
The new 452 heads has the spacer built into the head, so I need to get a newer rocker arm assy (less spacer),
There is one on ebay which I may pick up.   Thanks for all the other advice too.

  Mark,

  I seem to recall that the original lifters used in the early 383/413 engines
  are no longer available. If you installed mid/late 1960s 383 lifters, they
  are a different length. If you get a set of the corresponding later
  pushrods, they should compensate for the new lifters and work ok.

  Maybe someone else can confirm?

  Jim

  Hi Mark,

  You can buy push rods in any length you want from Crane and other
  manufacturers. They even have a tool for measuring the proper
  length. I would think that later 383 push rods would fit?

  One thing to be aware of is that 1966 was the last year for the push
  rods with the indented tip to fit that hydraulic lifter. If you get
  newer style push rods, you may have to change over to the newer lifters.
