Hi, I have a 1996 k1500 Z-71 with the 5.7 vortec. I'm going to be working on after this winter. I know, it's not an lspowered truck/car, but there are lots of ya'll that have experience with the older lt1 cars. Stock these trucks put down 200-220 and around 300-315rwtq. I haven't had it dyno'd, but currently I have longtubes/CAI/true dual straight pipes, x-pipe in place of cats/ Ed Wright custom tune. I have seen trucks with the same engine and similar mods put down 250rwhp and around 330rwtq. I am going to be getting my vortec heads ported and running 918 springs along with 1.6RR's. I plan on throwing in the lt-4 hotcam and 2800-3200 stall. Also, have a marine intake with 30lb/hr injectors I am throwing on it as well. Regardless of numbers she puts out, it will be a FUN combo.

So, take guesses.

Thanks

I looked around and found a truck with basically the same build as me, but he had the stock vortec intake and crappy injectors. He put down 303rwhp and like 380rwtq. The marine intake is good for around 20hp is what people have gained on the dyno. So, if I'm lucky I'll see around 320/380-400.

should be a vast improvement either way
