    Default 7.4L vortec black box

    I recently bought a project car that has a brand new, bone stock 454 engine in it. The computer running it is 16244210. I've gotten as far as finding out to tune it I would need a a 0411 pcm and that I would need to contact Lextech for a pinout. I've tried to contact lex via multiple sites with no response. Most of the forums doesn't have him being logged in for a good 6 months now.

    I plan on sticking a zz502 cam in it, although I haven't done much research, that's down the road. The trans is a 4l80e and I need to find a cheap solution to correct the gear ratio. I've never played with tuning software, not sure what the expense would be for a cable and software.

    Hopefully the lights are still on in this subforum - this engine and swap is a bit dated now.

    thanks

    I'll send him a pm on your behalf (the forum won't let you do pm's until your post count reaches 10).

    Jeepster,
    You aren't set up to receive PMs either. I just tried. Go to the "Profile" section and check to receive messages/PMs.
