Disconecet batt undo fuel lines ,linkage&any vacum lines pull distrb. remove all manifold bolts and 4 carb bolts. Pull carb and then use large flat screw driver to "pry" manifold up to break the gasket seal.

Install in reverse then bring the #1 cylinder to TDC when droppin the distrib back in pointing to #1.

Check all fuel lines to make sure thier tight before you start it and the most common problem will be the chance that you may be 180 off on the distrib. If it back fires through the carb then you are 180 off and you will need to pull and reinstall the distrib reposition 180 degree.

one thing i always do is to use a shop vac and suck up the dirt & junk as i'm scraping the old gaskets off to keep them from goin into the motor.

hope that helps a bit its a pretty simple job.
