you did make sure the distributor is installed with the rotor contact pointing at the 6 inside the triangle while cylinder #1 is at TDC, right? Don't trust the marks on the balancer since there is 2 of them.

Didn"t move the crank sence installing timing chain. There seem to be 2 timing marks on the cover that line up with both marks on ballacer .

Fly wheel is back on. Spent today working on transmission cleaning the gasket off the transfer case mating surface ,changing the filter , and welding up the hole the salvage yard drilled in the pan. Engine stands also work well for tranys . finished by raising the blazer high enough to roll the trany under it on a trans jack.

Re: Things to do before installing 4.3l in 97 blazer
 

or remove left mount through bolt, lift engine with block of wood and jack, and slide lines between diff. and pan.

did you replace vacuum switch on top of transfer case? They go bad and worst case they send ATF into every single HVAC actuator (big job replacing) and the front axle actuator.

Re: Things to do before installing 4.3l in 97 blazer
 

No ,didn"t replace the vacuum switch don"t know much about these things or 4x4s.Wife bought this thing without me and the first thing I had to do was to re build the frount end ,ball joints a frame bushings pitman arm and iddeler arm. 4new tires, the rear had 2deffert sizes ,you know what that means.
The oldes one drives it and I haven"t figerd out how she killed the engine and trans at the same time.
Used the jack and block of wood ,didn"t take the left mount loose barly worked it through .

Today changed the spark plugs, 3x platinum, set gap at 60, old plug were 80+. Put exast manaflod on bolt up y pipe.
also freed up the flair nut on the egr tube and reused it.
