4.3 TBI to 350 TBI swap

[PlayingWithTBI]

It has shorty headers, No EGR, or cat. Other than, that stock.

You shouldn't have a problem starting up. Pay attention to what you have to disable so it'll go into "VE Learn" such as CL, HiWy (if you have it), EGR, & PE (in Scalars) - set them all to 250+. Then set the BLM Max/Min (in Tables) to 128. I strongly suggets you get a WBO2, it'll even tune up to WOT. All of this stuff is in the instructions on the CD. HTH

Do these trucks have shift lights? If so, how do I make the one I have on my truck (stock cluster) work with the flash-2 system? Or will it just work?

Thanks!

Anything on this?

Do you really want a shift light? The factory has the shift light set for maximum fuel mileage and it can get annoying.

You kind of have a point. But, I would still like it to work, if I can get it too.

Yes it has one and you can set it to whatever RPM you want. I think it uses the output that's for the TCC on an auto trans but, you'll have to confirm that.

Now I'm having an issue of finding a fan shroud and rad that will fit each other. Currently, the rad I have sticks out passed the fan shroud. Is this okay? Can you guys help me figure this out.

Thanks!

"sticks out passed the fan shroud"

What does that mean? Photo?

It should be fine, but you're not getting the full cooling capability of the radiator. Just make sure the edge of the shroud isn't digging into the cooling fins.

I mean a portion of the core (on both sides) and the tanks stick out of both sides of the shroud. Unfortunately, I feel like my description doesn't make any sense, and I don't have pictures because the rad is not in the truck at this time.
