Default power estimate on lq4

think you guys could tell me how much power i should be looking at? setup is-
lq4 bottom end with arp rod bolts
238/242 .580/.590 112 cam
cnc ported 806 heads
.042 felpro's
edelbrock victor jr intake
holley 750dp
modified factory manifolds with 3'' outlets (i know but its the best i can do without gettin a k member for now-mustang)
msd 6010

this will be through a turbo 350 with a 3500-3800 stall. what you guys think?

im not sure what your setup will make but i read in car craft magazine about a 99 lq4 motor they put a carb on and it made 450+ i dont member the exact numbers but i do member it was 450+. they used a 99 lq4 stock bottom end and stock iron heads and stock cam. a edelbrock mani msd box and a 750 holley. but also ran long tubes. hope this gives you an idea.

They made 425/439 on the stock cam. And that's crank hp, not wheels, which the OP is probably looking for. They made the 483/450 with a GM hotcam. I don't know why they didn't spin it higher than 6k though, because it made the 483 at 6k, and the chart doesn't go on after that. Maybe it says in the article, I just don't have time to read it all now. http://www.carcraft.com/projectbuild...t_results.html
