I am dropping in a 496 BBC into my old camaro project, and I know the 4L80E is really heavy, and expensive. I was just wondering if the 4L60E can be built to hold 800+ rwhp? (I have a 4L60 sitting , just waiting to be rebuilt) Thanks

 

No. I don,t believe anyone can build a 4L60/4L60E to handle 800 horse.
Rossler is probably your best bet with that kind of power.
