tore apart troys 1500 the other day

truck fun, not fun of course

pulling more out of the truck... i yanked the cam today, with a dowel in place, and the loosest lifter in the world went strait to the windage tray, lol! first time that has ever happpened, so that sucked, had to pull the pan and tray, luckily i could do that while it was installed, wasnt too bad, then tore off the cyl head and reinstalled it after i got the cam in, and everything seems good now haha, got the rest of it buttoned up and started filling the block, gotta bolt up the converter and then starter and see if she fires.

started tearing into the engine today

i got more shit today, turbos, wastegates, transgoHD2 kit for the 4l80e, i got emails today that the cam and the converter shipped today, might get them before the weekend too!

started tearing down the motor for the cam and head swap, and had some fun with the plasma cutter.

broke the fresh 5.3 already

ok, so i took it right to the dyno friday, black friday, and hit it with 20lbs and she made 40rwhp extra, 640rwhp...


so i proceeded to top out the boost controller again around 26psi and it came up, and stumbled and laid over. i let out and knew i broke a piston or two again.
rods are strait. 
piston 3 had the lower ringland broken in half...
im at a loss here haha what do you guys think.


3 and 7 are broken the others are fine. used headgasket is fine also. pistons dont even have any marks in them showing detonation or anything.

tear down and overview of the 5.3 i have been thrashing like it owes me money

fairmont 5.3 teardown

exciting to finally tear this motor down and check out what i believed the ring-lands to have butted and broken some ring-lands. to prove this we would have to see spotless pistons and broken lands only.

its nice to see we tore it apart and found exactly that, broken lower lands, from butting and perfect piston tops, people are also right about gen3 rods bending at 650+ because every single one of my rods is bent slightly lol. it seems like the rod is heaver material wise on the one side and thats the side they bend towards, hard to explain but they all bent around equally in the same direction bowing out in the center twoards the flexplate, rear or the motor.

should get my gen4 rods and pistons tomorrow and ill be opening up the gap on the rings and throwing them in.

it was neat to see, since pistons 1-3 broke, we checked the gap on them and they were like 18-19, then checking the gap on the other pistons that did not break, some were 24... just re confirming what people say about when you are pushing them you need to open the ring gap, but honestly it took bending the rods to break a ringland on this gen3. so i would say 600 is your limit probably might even be slightly bending rods at that power level.

Bad Lifter found!

found the bad lifter and i picked up a spare 6.0 short-block today



Found you! Video
