Ran into a snag working on the fan pulley tensioner on my "64 383. Bolts that hold the tensioner bracket are the two front cover top right bolts. These are stuck tight. Used the usual trick, tapped the head of the bolt, used the impact in forward and reverse, taped the front cover where is meets the block, all to no avail. These are apparently grade 8 bolts, but I an afraid to really get on them with a breaker bar for fear of breaking them. Definitely don't want to break them an end ip pulling the front cover. Suggestions???

Might have to just man up and crank on them with a breaker bar and see. Those are long *** bolts. Could be siezed in the extension part. Rarely siezed in the block. Pulling the water pump housing is not a big deal and new gaskets probably wouldn't hurt
We've had some good success with an induction heater.
Heat and cool a couple times then try with a smaller impact (hopefully not strong enough to snap them)

Just going to have to apply force. They are 3/8" bolts and won't break very easy. No way to get penetrant in there. If they break then have to fix that.
The top bolt is behind this water pipe. To get it off use an open end wrench after all the others are loose. Leave it captured behind the pipe. Don't remove the water pipe.

Break out the torch, but make SURE you get that fuel line empty & maybe using a “heat blanket” and have a fire extinguisher handy
Agree on heat from a torch, usually works but I'd temporarily empty and remove the fuel line while using the torch.
That's why an induction heater is better.
Once you use one a couple times you forget about a torch.
Thanks to everyone for their suggestions. Talked to an engine builder today, he suggested drilling a 3/16 or so hole in the water pump housing to the depth of each bolt. Heat the housing along each bolt and dripping beswax or candle wax into the hole and let is disperse throught the rust.
I have used beeswax on stuff including siezed big truck lug nuts abd frame bolt nuts, works pretty well.
Going to try your serveral suggestions tomorrowm if no luck, try the drill idea.
Thanks again!
