The answer to the bore question is in the archives:  1-11/16" for the
4.3, 5.0, 5.7, 2" for the big block, and something smaller for the 2.8
v6.  Injectors vary, there is more info on the gmecm page (click
component info, tbi and injectors).

I don't think the 749 can drive 4 peak/hold injectors.  Where did you
see that?
