19965.3LW/T

I got a 1999 5.3l in my 1996 pickup. Im lookin to put a cam in it with my next paycheck. i want to put the biggest cam i can put in it without haveing to change anything else. My limit to spend total is $500.

Put that $$ in a place you cannot touch it. Save another similar amount then pull the trigger.
Why? Because along with cam you'll need supporting hardware: (springs, timing chain, pushrods, fluids, gaskets and of course tuning)

Predator is the zo6 cam good for the 5.3L for a turbo set up?? im going to be using the pt88 and want as much out of the engine as possible

why so big of a turbo? are you running a big converter?

z06 cam makes good power but im not so sure if it will be enough for that big turbo

I would need way more info than this to know which cam would fit in your parameter setup, but right of the bat I would say no on the LS6 cam due to the size of your turbo.

sorry for the hi jack op... my goal is 800 with this motor i looked around and it looks like the pt88 can get me there, car will pretty much be just a track car with th400 and 9" still need searching to see what stall and gearing will work best for it 28" tire

To make these numbers, I would be looking at a bigger cam than LS6 and with some overlap. I cannot be more specific without complete combo info including specific turbo info. In brief the whole enchilada from front to back bumper including weight etc....
Read around the FI forum and dyno forum a bit, you'll get more info and get a clearer idea.
