I may keep this engine in her for KOH just because backdoor always seems to try to kill bearing from lack of oil PSI, but then the desert party wont be as fun with 200 less hp.....decision decisions
Waiting on the valley plate to throw her all back together and then see if i can shove her in the toy hauler on rollers to get the can-am in there as well. Jenga time
Nitrous?
Least you learned something in all of that checking/rechecking/checking again 👍Well goodish update?
Finally had sometime to change the oil and check lash, cut the filter open and no shinny's or particles so that's cool. there was a little more clumped on the magnetic drain bolt than id prefer but its also a 60 year old short block.
I pulled the lifters again because i thought i was being dumb, i couldn't find a lash spec on the cam card details (photo of a photo from the previous owner) and lo and behold i was. They're hydraulic flat tappets. Went on summit and found the cam just to verify and it is indeed a hydraulic.
Reinstalled the rocker rod and torqued down, then checked every valve using good ole mama Mopar's 90 degree technique. Somewhere in the neighborhood of 4-6 had little no preload, with 2-3 of those actually having significant gaps.
So my hope is that while the oil is thick/cold they're pumped up enough to bridge the gap and that's why they're not making noise and at RPM/Warmed up the oil thinned and the gap is causing the tick.
Milled the heat crossover off the bottom of the RPM dual plane manifold i have because id like to keep it instead of going to the single plane, and the new valley plate doesn't have room for the crossover. And blocks it off at the heads.
Gaskets and plate should be here today so i can bolt it back together and see if she's fixed or if she's going to have to show me what's wrong
Just like the old saying goes, "I'm not the fastest Crayon in the shed, but even a squirrel finds a blind nut from time to time..."I mean i already knew i wasn't the sharpest crayon in the box
Nice.Small Update:
Noise is gone. 100% was the valves out of adjustment/no preload on 4-6 total. Kinda wild to me they backed off that far. Engine is significantly quieter as far as mechanical noise, funny how that works
They make adapters so you can install a proper GM transmission that works behind your POS with properly adjusted valves now

Or, going to a dedicated standalone controller with no OEM ECU will solve anything electronic. I have contacts if you so desire.
The external aftermarket TCU gets rid of the OEM VB and controls the solenoids directly.
My contact doesn't deal with the same system you have.

We will help you get rid of the OEM TCU that is integrated in the VB and replace it with a fully programmable external TCU.

Very.
not really ideal timing, not that it ever is. Also pretty disappointed it was cruising at 50-60 on a two lane road and not ripping through whoops at 70 and 5k plus RPMS at least id feel justified then.......
He's one of the many guys I use. Different applications require different people.
Sell the stuff an move on. You'll wonder why you didn't do it before.
KISS, always.
I am all about "8HP the world" I have the 6l80 in my rig right now and when I bought my 6l80 years back I really wanted to 8HP swap mine but it wasnt nearly as common to put an 8HP behind an LS at the time.
Maybe a nice chevy 305 would be good fit, reliable and basically same power as a 440.
