I dropped the 454 crate motor in the 78 rs and had everything hooked up. Poored some oil in the motor some coolant in the radiator and called it a night since the garage was closing and there is no arguing when they say its closed its closed. I get a half day off work the next day to go fire it up. I check the fluids.... oil, check.... coolant..... damn it! where is the coolant?! on the floor thats where. The motor had a cracked freeze plug! It happens to be the one on the passenger side under the motor mount. I tried putting in a freeze plug with out pulling the motor only to end up bending the hell out of it and making that one leak too. So now I am gona go to the parts store and buy an "expandable" freeze plug so I dont have to pull the motor yet again.

This ever happen to anyone? Any tricks to installing a freeze plug without pulling the motor?

Years ago I used one of those expandable freeze plugs on a car. I had serious doubts about it. But it held up and I didn't have any problems. Hopefully yours will be good too. Make sure you clean the freeze plug hole completely.

Wow that stinks. You will get it going soon. Then post up some pics or a vid. Would like to see!
