View Full Version : Needing Early Hemi Help

I'm in the process of a total "Upper End" rebuild on my 1966 Dodge Hemi Charger. It still retains its original 426/425 Elephant engine.

Question: Although the factory, stock pushrods look decent, I am contemplating replacing them. Before I go any further, could one of the forum members please describe for me what are the "factory standard pushrods"--diameter, lengths , etc for both the intake and exhaust valves.

Question: Is there anything on the market that is better than the stock pushrods, recalling that I'm keeping everything pretty much "standard"? The cam and crank are unchanged. I did install new valves, valve guides, springs and rocker arm assemblies but all to OEM standards and I did "hardened" the valve seats.

Last Question: When all is put back together, what are the correct intake and exhaust valve lashings?

Many Thanks,

Rick

Rick -- I'll look at some of my old manuals in the shop tomorrow for the valve settings ... TAZ

Any available specs on those Smith Brothers pushrods?

Many Thanks,

Rick -- one of my old (and I mean OLD) Motors manual indicates the cold valve settings are .028 intake and .032 exhaust. TAZ <<GRAEMLIN_URL>>/beers.gif

THX Taz.

Do you happen to know the diameter and lengths of the pushrods, both intake and exhaust? I did find the Mopar part numbers--2468092 for the intakes and 2468094 for the exhausts. The parts catalogue gives the part numbers but not the technical specs--at least the one that I have.

Went with Crower. They provided really helpful assistance.
