hit it with the juice. I made 350 to the wheels the other day on a dyno.

cam / converter / 100 shot

Rob (vortec350ss) specced the cam

 

Your cam is mild though. This guy wants to get more aggressive than you do.

 

I think I am close to 400hp. but have not dyno'ed. 2002 LM7 5.3


275 HR cam 400
Springs 200
Torqu conv 300 (made at local trans shop from a colorado converter)
Tune 100 (friend has a HP tuner)
flex fuel inject 60 (used)
adapter for injectors 20
cold air e bay 90
headers long 550


total 1720
exhaust cut out 225 (electric flapper), I run bone stock muffler and beyond.

 

My daily driven 04...... stock with e fans and a nitrous tune hitting it with a 150..... awesome 4wd launches

 

how much juice can i handle for how long safely

 

400 hp with 700 is not going to happen, unless you spray it. i would just do bolt-on stuff speed engineering has header for 230 plus shipping, shorty dont do much. under drive pulley, junkyard e-fans, trutrac with 3.73-4.10 gears. or just save little more go ahead and do the 80e swap.
