So - I disassembled my 6.1L Hemi that is going into my 68 Charger... it was advertised with a "spun bearing" so I got it for $2000. I disassembled it tonight and was flat out horrified...


7 out of 8 connecting rod bearings were spun!!!

I have never seen an engine have that... NEVER... and I've taken a old big block 426 Hemi to 8900rpm... Creepy... guess someone disabled the rev-limiter and had a little too much fun.

Oh well - will give you guys an update when i know how much my machine shop bill will be.

That sounds like oil starvation  :eek2:

Hopefully the crank isn't cracked....send it off to be magged  :scope:

Agreed and it wouldn't hurt to do a little investigation into just how the oil starvation happened.

It was in fact a warrany replacement and mopar did not want this bad boy back...      seems to be very likely this is the same motor...       care to share the info you have ?

same engine!  I was told it was out of a Challenger and sent to a tuner and it came back with a rod knock...      had all 5 mains spun and all 8 con rod bearings spun...        never over 4000rpm...     hard to believe...      it looks like it was rich as there was quite a bit of carbon build up...        maybe leaned out then richened it and spun bearings sometime in there....           

Still - not a bad deal for $2000.  I scored a NEW crank from a dealership for $350.00 + S&H...     Bearings are like $150.00 ish so...    I'll have her back together and for well under $3000.00 - - -

well the owner never rev'd it for fear it was too new... the tuners wrecked the motor and pulled a ton of timing out of it to mask the knock.... other than the bottom end the motor is practically new....nice score... hope u have more luck than he did.... he now has a new tuner new motor and runs great.... some lesson on the behalf of the tuner....

Small world isnt it ?          All i got from that car was the Engine and the harness....      The Harness itself is $995.00 of you buy it new...     Good thing I forked over the extra $50 for it. 

Got a quote on the new Crank - final price is $380.00 shipped to me with the tone ring.  I have a guy who wants to pay me $150 for my old crank so...     not a bad deal...   

Please post the Tuner's info when you get it...   


PocketThunder...     been posting little updates here and there...   I'll probably start a thread when the car comes back form paint and body and document the entire "building process"...    The engine build will be included in there too - most of you guys probably havent seen a disassembled 6.1L go together so it should be fun...
