Well my 4.3 98 blazier overheated (she drove it till it died), replaced waterpump, head gaskets, intaketake gaskets, new plugs, (I had water coming out of exaust). Well I think I fixed that problem, went to start it up and it starting backfiring through the Intake, It runs ruff, checked the plugwires, coil ect> I marked the distributor and installed the same way it came out. I am wondering if maybee it got so hot (300+) that I fried the distributor or maybee injecters???? Help!!!!!!!!!!!!!!!!!!! Thanks Zeb....

 

Most likely didn't get the distributor back in on the exact tooth.
