Locked up Slant 6

Oh, without a doubt she needs a rebuild at this point, I'm just hoping it frees up to make Your life easier. Both removing it & pulling it apart to rebuild.
Are You using the crank bolt from a big block to try & turn this puppy? dirty white boy made a couple of good calls, I just picked up a '62 valiant 170
& the water pump was locked up solid, also it's a long shot but the starter could've stuck engaged & is frozen up itself...good thing it's a slanty......
easy to pull!!! The valve stems are easy to check, put a small section of furring strip etc. on the rocker above the valve & give it a rap w/a med hammer.
If it bounces your good, don't worry about touching the piston, they're a good ways down even at TDC. Unless You really slug it, You're not shootin' for a
prize at the fair!!:D
