Looks good but it was 112mph at 6600rpm. The converter is made for a purpose but not the power level he is at. The lockup in it could not even hold 380rwhp without slipping.
My car ran 120mph with a Yank 4000 stall at 6300rpm(roughly), same tires/gear.
Either way,too late now. Now I'm wondering if the motor was overspun and ate up some main bearings.

and as for the 110mph I was unaware that it was at 6600 I was told the car only revved to 6100 or so......also why would you even want to rev the car that high espically with 12lbs of boost on a stock 155k mile shortblock?? seems kinda crazy no?? regardless of the size of the cam in the car.....
very funny

You must forget my car.. Single disk converter locked up perfect to make 580rwhp a ton of times. Car above has a 4cyl lockup disk in it which is why it doesn't hold.
6600rpm is not a problem. You obviously didn't come to the last dyno day to see Sams turbo car with a ton of miles making 660tq/630hp through the 4l80. Or the 2 Avalanches that run 16-18lbs on there stock blocks revving to 6800rpm. It can take it BUT it can not take a hammering on the rev limiter which will easilly walk the caps and eat main bearings causing low oil pressure..
Sometimes engine just fail.

and i was at the last dyno day..........and I understand the 16-18lbs of boost in a 5.3L but they do have another .100 on the cylinder walls and less surface area on the piston...........but i dont have to explain that to you.......
like i said you are a experienced shop and i respect that........and as we both know its about the power you make AND the durability of the design........seems like so many guys are good at one but not the other......
