What is the intial startup/ timing procedure for twin 5.7gsipefs that were upgraded to new gm 6.2 long blocks? I used all old stuff off original motors intake, tbi, distributor, etc.. I had mefi bob reflash ecms for the bigger 6.2 long blocks. Can't get motors to start/run. I set distributor to tdc #1 compression stroke will not start. Per the manual I am trying to get it to start/run and get warmed up then put it into base timing mode with my laptop running rinda diacom, and set it to 8* BTDC with timing light. Can't get that far. Am I supposed to put it into base timing mode upon intial startup right off that bat?
