Frankly, I'd be a bit scared at this time. Want to pull the motor, pull it down for a good inspection and fresh rings/bearings and let it sit unfinished for years.....
Well Don.... that's a long story. It's a stock Boss 302 Coyote block. It was very carefully blueprinted by yours truly. Stock crank...Eagle H beam Rods, CP Pistons, 11:1 actual compression ratio. Billet oil pump gears, and arp fasteners. The heads are Boss Coyote...CNC ported by a good friend who almost forced me into letting him play with them...stock shimmed valve springs and valves also. So... in effect a almost stock bottom end with some reliability upgrades. And a almost stock top end as well....She spins it 7200rpm *usually which for a Coyote is conservative. So far no oil consumption or unusual issues. Given the engine has seen VERY close to 4 digit rear wheel numbers on a max E85 tune...the "around 750rwp" tune it usually runs is rather low stress. At least in theory...Much less stressful on me anyway than the 6 dyno runs to 8400rpm we played with this fall. But WOW at how much HP is hidden between 7200 and 8400 rpm...and it's a head rush to know with a tank of E85 a laptop and some slicks...mid 9's are a reality.

OK, copy thatIf you were in that bottom end already, We can rest assured it was done correctlyNorm, I am floored by the numbers these motors these days are capable of!Nearing 1000 RWHP if beyond comprehension. That's 1200 or so at the crank, unbelievableBut having said that I remember once watching this project build. Point was to see if you could take a junkyard run of the mill 5.3 LS style motor and get it to make 1000HP on a stand before grenading it.So I believe the plan was to test it, replace the head bolts, pull the pan for inspection, small cam, then add a turbo.And the test began...It made 500, 600, 700, and they thought it was going to fly apart, so the decision was made to push it to when it broke.Injectors, valve springs, more boost, less timing, better gas, and 800, then 900, and then it produced 1000!A used 5.3L Chevy truck engine!!!!!Not satisfied they ran the boost up even more, and it passed 1100HP!!!!They pulled it again and it made a documented 1267HPandIt didn't explode!So these guys pulled it down for a close inspection of the pistons and rings and rods and so forth.That's when they made the discovery that sent this thing into orbit.It wasn't a 5.3!Nope,IT was a 4.8L!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Don.... Is this a bad time to mention Stewie needs a truck? I really can't be fired since I have no responsibility here...but if it helps, you can fire that fella In hippy land in my place LoL Word has it he's likely welding in his Jesus sandals right now on a Jeep.
Oh, might as well announce here as opposed in another forumTexasRedNeck is no longer with us....

I might get promoted yet.
Did I get that wrong, about that 5.3 being a 4.8?CRS again...or CGTR
As much fun as all this new technology can be...I am looking forward to the M37 no technology build. It won't have 1000hp or fancy gadgets...but it will have what I cherish most in a truck....function.

I just don't want to wind up missing a digit or limb. I can sometimes get in a hurry to get results.
Waitin' with baited breath!
I used to keep a few hundred pounds of sand bags in the bed of my 77 so it handled better.

Update: Where to begin...Patch: the lift pump died. I took the doors off Patch and put them on a club cab gasser, and have been using that. Patch has been resting comfortably while life keeps me busy, so it's future is uncertain. Anvil: got a lot more use this summer. Like 10k miles or so. Other than a recently developed small injection pump leak, it has done all that's been asked of it. Kay's Mustang got the most attention. Autocross, drags, just driving..lots of subtle under the skin suspension mods, just drove it to church yesterday. Winter being almost here I imagine it will get little use now tell spring. Kays been making noise of selling it and buying a Vette....who knows with her. It has a whopping 6k miles or so on it these days. Kay and her oldest daughter bought a 2015 Crew Cab Eco Boost F150 4x4.... it's almost everything I despise in a truck.. heated seats/leather, gadgets, technology. It gets the worst mileage towing of any vehicle I have owned EVER. Short little box on it makes it a girly truck. It does have 34.5" rubber, a locking rear axle and despite it's appetite for fuel when towing....it can haul 10K lbs at 75 mph rather easily. It's growing on me a little....The newest member of the fleet is a 1981 Chevy Standard cab heavy K10. Complete with a nice functional steel flat bed, a 383 small block and a 4speed. It needs a flywheel to be driven....so maybe soon I will have a chance to make that happen and then who knows what we will do with it. The plan as of now is to make it run and sell it. Before Kay gets any ideas and decides she needs a Cummins powered Chevy. I have an entire house tore apart in the middle of dry walling/electrical upgrades/flooring I am suppose to be working on. Too many irons in the fire ATM In the addition to all the above going on, I am trying to find time to put together a new "shop" in a building in town. Roughly 28' x 35' Nice flat floor, large garage door and lighting...its basically bare. I need to wire up a welder outlet, put a air compressor in there and I suppose I could get some work done. We did move some of the tool/equipment down there a few weeks ago. At the moment it's keeping Anvil and the Chevy out of the weather...that's about it.
At least the new truck has twin turbos!Please don't tell me in all that "stuff" you got a flywheel can't be found?
