Using TBI on moded 5.7

[Mike Vannorsdel]

I have a '91 K1500 with the 5.7 TBI.  I have just rebuilt the engine and
made a few changes.  I have raised the compression to 9.5 and added a
CompCams XE250(250/260).  What, if any, changes should be made to the
timing and TBI to work well with the changes?
