About 30 lbs of caustic soda, or lye. Set up the barrel up so that you can get a little propane barbie' (as in, que!), put about 1lb of soda to 1gal of water. Strip the block, don't forget the cam bearings. Load the barrel, you could even put some simple green in as well, rember the displacement value of the block, don't fill to the top just enough to cover the block. Start the burner and heat to about boiling or thereof, that mixture will eat all the crap out of the block and leave you with bare iron. Keep an eye on it. This is basicly a old skool hot tank. A lot of trouble to be sure, but when you are working with 70-80 year old engines, ya gotta do what ya got to do! Now, the powers that be really don't like us rebuilding that "old junk", we're 'post to go buy a new Honda....mmm, not me. Alleycat
