Started a new project.
Since my signature car is working perfectly, I decided to look into the Hemi to see where the oil pressure is going. Surprisingly, it's a very easy engine to remove. Turns out the lifters are very loose in their bores, that's where the oil is going. They can be sleeved back to standard size. Looks like it will also need a crank, as it's undersize beyond specifications. Note that the rings aren't even broken in, their end gap is well within specs. It's built like a tank, I guess that's what was needed for NASCAR racing back in the day.

What car did did it come from?

Any history on the motor? ( rebuilds , miles )
I'd be real concerned about the standard eyelet retaining rings for the piston pins. At high RPM the locks can distort and escape the bore with predictable results. Spiro locks are much better but have a go at research for your self as it's your motor. Go to Speedtalk.com there are some very sharp people there. |

my guess would be out of the coronet it's setting in front of.66?so how many miles on it to wear the lifter bores out?

I don't recall '66 Coronets having Hemis? 383? Possibly, but not a Hemi. Likely a 318.

I am amazed that the crank is overly worn. It is steel I assume. It must have been driven with very dirty oil for a long time. What a robust motor!

Nice to see the pictures - sorry to hear about the oil pressure trouble - you should have just carried on with the other thread...
...what are you going to do about the crank? ...what are you going to do about the lifters?

You're right about the thread. I assume the crank will have to be replaced. The lifter bores will be sleeved and honed to size. The nice thing about this engine is that I can go to the local Dodge dealer and buy parts for it.

I hope your Dodge dealer experience works out nicely for you. Bummer about the crank - though I guess that might be cheaper to source on the internet. Seeing as you've got everything out, are you thinking about balancing the parts (equal piston weights etc)? With the drag racing history, however, this might not be necessary as it could already have been done...

Took the parts to Ray Barton today. He told me that those are 12.5:1 compression ratio racing pistons. I can't believe how well it ran on pump gas. It's getting honed to .030, new pistons, rings, rods and crankshaft, in addition to having the lifter bores sleeved. It should be much better than new when it's done. The rotating assembly will also be balanced. I'm going to have to go into the mattress on this one.

What are the miles since being overhauled on the 426 would you estimate? Since you're finding such wear? *Xtra info on my neighbor's '64 Fury 2-door hardtop 426 c.i. 4-speed: It's been re-painted (white), but it's sounding possible that the rest of the entire car is original. IF, it is, and it's that ultra-rare - then - according to the Pacific Northwest MoPar Guru - it may be that he's sitting on a Super Old School MoPar at a cool $100K in present value/worth. Backstory on the Fury: Neighbor saw it on YouTube at/from the same dealer - KustomKars in suburban Seattle, WA. that Tyler Hoover bought his old early '60s 2-door, non- air-conditioned Chrysler Imperial from. Procured it from KustomKars somewhere around $22K - delivered. This approx. 1.5 to 2-years ago. There's a YouTube (or was) on the ride-along with the boys from KustomKars on the Net, when it was FS.

X2 well worth it!
Besides the princess will always feel the pea even if the mattress has a little bit less stuffing in it
