what did you do (replace it) if you still have a miss you may need to tune it up / make sure the fuel pump you bought is for the right psi for your blazer

Could be the EGR valve or the idle adjust valve. Check Engine light on? Any codes?

i have a new site for auto diagrams (AA1car.com) auto diagnostic &repair help,give it a try ,hope it helps ,good luck.

put four and a half quarts and start the engine check for leaks and check agsin

It's not worth doing all that conversion, buy the time you spend the time and money to convert the 89 4.3 to work on the 98 blazer, it would be cheaper to install a 98 vortec rebuild. The 89 4.3 have a TBI fuel injection system and the ecm on the 98 will not work and the bad news is that the ecm on the 98 also controls the transmission shift points and the 89 will not, so even if you swap the ecm to have the 89 4.3 engine work. the transmission will not shift. Sorry for the bad news but it would be cheaper to replace the 98 engine with the years of 1996 to 2001. Good luck and hope this helps. 

I'd say probably .060 but see sticker on rad support or underside of hood to be sure.

I think you are right about the starter being the problem; the whining you hear is the starter free-wheeling after disengaging too early.
Getting clearance is another matter; I have, on occason, used floor jacks to move the engine temporarily without unbolting the motor mounts but that may be necessary in some cases. Sometimes, I have just had a helper use a 2X4 to shift an engine enough to gain a needed 1/2" of clearance.
