All the crane golds for mopars are aluminum rockers running on steel shafts.

Usually fine (for a while) with spring pressures under 600lbs.

Neither; the aluminum body runs directly against the shaft.

rods 6.768 long h beam
crank mains & rod are std. 4.15strk both rods & crank are eagle
pistons ross 12.5:1 comp
mains & head are studs
mylodon single stage hv (have 2 stage set up )
heads mopar stage v 2.250 in. 1.8ex,single stage intake ,no carb,no dist,
no water pump(have used meziere electric,if interested this is option??
roller cam crane 1.5 rockers cam I believe to be comp cam

this, plus a rollerized A&A 727 with RMVB and aluminum drum for around 6500. other parts are available, but i don't know exactly what. my thoughts were to use my MW intake, and install with 2" TTI's in my charger after an inspection and refresh.
thoughts ?

if the rod journals are stock Mopar 2.375 size I would sell the rods and pistons and have the crankshaft offset ground to BB Chevy 2.200 size and offset to 4.300 stroke and buy some BB Chevy 7.100 long rods with the .990 pin size and buy a really good set of a lot lighter piston and pins up twocents
What size rings are on the pistons you have now?
If your going to race this motor only look at a skinny ring like 1MM,1Mm,1.5MM in all three grooves, not 1/16,1/16, 3/16 up scope

can't answer the ring package at this time cab. got to go look at this setup first. the pics were sent to me by the owner, who is roughly 125mi away from me.
looking to put my charger in the 11's if possible, without spending 15k. as it is, i will have to upgrade the rear [it's an 8 3/4, 742, 3.91 now] and driveshaft, plus frame connectors. the docs and hospital need "assistance" ya know ! biggrin
if all checks out as described, is this a reasonable deal ?

As has been mentioned....... with the heads having 2.25 intake valves, and not knowing if oversized seats have been installed to facilitate that...... they could be a big fan of worms.

Buying used race stuff is risky at best...... throw unknown stage 6 heads into the mix...... and the risk factor def goes up.

Perhaps there is documentation of exactly what’s been done to the heads buy the shop that did them.
They might be really nice set of heads........ but they also might have intake seats about ready to fall out.

11’s out of a Charger?
That’s just a flat top 440 with a decent cam, e street heads, an rpm intake, headers, 9.5 converter and 3.91/4.10 gears.

I wouldn't pay $6500 for that engine and trans even though I'm sure the guy spent a lot more than that to build it. The problem is that some of the information is incorrect so that makes you wonder what is what. Plus the engine in the picture doesn't appear to be well cared for. It has rust on it and it appears to have been sitting for a while. As pointed out before, Stage VI heads have a bad reputation. Maybe those heads are good ones, maybe they aren't. I suppose you have to go look at it in person and talk to the owner to know for sure. Good luck.

Where are you going to find a 6.768" H-beam rod? AFAIK they do not exist. Most aftermarket rods are 6.760. I think there is one 6.765 out there but it is in an expensive line.
