Im building a 2002 z28. Powertrain will be a 408 stroker. This is the first time I have built an ls stroker. I have a 4.100 crank, 6.125 rods, 11:8-1 arias pistons,and starting with a set of 243 casting cnc poted heads, in front of a turbo 350 tranny with a ptc 9" 4800 converter. The rearend is a 9"ford with a 430 gear ratio, 28×10.5 tire,its also topped with a victor jr. high rise 4500 flange intake,with a aed 950 carb. Can someone please tell me what I should be expecting as far as power and performance???

You won't have a 408 stroker with a 4.1" crank unless you have a 3.98" bore.
What cc chamber are those pistons rated for 11.8:1?

You haven't said anything about cam or vehicle weight, so nobody can make guesses as to power or performance.

There is a 408 sticky thread in the Dyno section.
You can look around at those set-ups and get a ball park probably.
