... too bad for me the engine builder eddie haines lives in florida, and i am in oregon.....
There's always someone fairly local that can build a hot street hemi motor. Might not be next door, but closer than the opposite coast.
More things going on in a motor than a paint job, rear end rebuild, or wiper motor re-build, etc...

backstory on this motor, this is an earlier mopar performance block, (pre world product i believe?) it has a full water jacket, not siamese bores...... anyway, here was the deal: the block did in fact have a casting issue, and was leaking out of the main oil circuit. it did not rear itself as a problem until the engine was good and hot. eddie haines had the machine shop bore the passage to 3/8"s, then tolerance fit a thin wall tube that was loctited in. he then epoxied over the repair on the outside, for insurance. that took care of the oil leak...... the blowby issue: the diamond pistons were .0005 under tolerance in the ring gap, they were supposed to have .0015 clearance, and only had .001. is his words, some of the rings seized up in there because of this. he did not notice it on fire up at his place, i didn't notice it until it had run for awhile. so, diamond says they are within their spec, but the total seal rings did not like it. a new set of pistons would have taken 8 weeks, and they said they might be just the same dimension wise. so, a new set of rings were sized a half a thousandth off of the thickness, and used..... this all took place without any discussing of the matter with me or my partner. the work had been done, and the engine put back together. i told him how i was not comfortable with this, as we were already in it deep enough with the first set of problems, and doing this again coast to coast was not an option, not after this much money has been spent. so, against my gut, i decided it would be ok if the engine were dynoed, cooled down, dynoed again, video'd, pics, etc, to verify everything was coming up good..... the engine was broken in on the dyno, no blowby, and made 576hp and 543lbs. ft. of torque, at 5800rpm. he said the lifters begin to pump up after that in his past experience, so he didn't take it higher. he thinks there is still another 15hp or so there. there were pics, and vid, and everything looks to be good. it was not heat cycled like i asked for whatever reasons....... so, engine back from florida, installed, timed, and ready to go. lets try this one more time... stay tuned for the next exciting chapter of the drippy hemi saga......

all this happened in 2 days ?? Your picture of the motor heading out was on Sunday - do you own a teleporter ??
ha! let me clarify: this project is not quite in "real time" on here. i am further ahead than what you are reading, as i started this thread after i already begun the project, (by a couple of months), and am catching up to real time.
i am posting this 'as it happened when it happened in order', and we are almost in real time......
so, i didn't mean to confuse anyone with the time frame of this project, but i still want it to read as a progressive project in retrospect when it is all said and done, regardless of actual time stamps, when people read this thread later.
so, that is why things sometimes happen 'faster' than humanly possible when i post in here, at least for the time being. i hope that doesn't bother anyone, i just want to share all things hemi cuda project with all my fellow car peeps. either that, or yes, i am a superhuman gearhead with amazing super time defying powers. yeah, i like that....
thanks for understanding,
D
