    horsepower guess for new lq4

    so i got a 99 lq4 from a junkyard. i put a comp cam in it ( dur at .050 208int/212 ext and valve lift 554int/558 ext.) and beehive springs. got long tube headers and intake. and nelson performance custom tune. i was wondering what kind of hp and tq numbers you guys would guess it is putting out at the crank. i need to find a new tranny and i need a estimate to find the right one. thanks for the help!

    Get a trans built to handle as much as humanly possible. There are "1000HP" transmissions that dont hold half of that power.

    The difference between winning and losing, is having a 2nd stage.
