LT4 hotcammed L98 running NOW!!!!!
Fired it up last night. Runs pretty good on the Hypertech St2 chip I had in it. I just set base timing at 8* BTDC and fuel at ~ 45psi and then reset minimum idle. I can't believe how good it runs just like this. All mods are in sig. Can't wait to run it now!

re:
I'm not sure how much. I haven't checked it yet. It does idle pretty decent though. I may need to drop base timing alittle and then set the idle higher. I'm not sure. Its no where completed yet, but IS very driveable unlike what I was told by many members on here. Now I just have to get the tuning straightened out so its running close to perfect I guess. I'm very impressed so far.
