I recently procured a 1958 Chevy Delray that has been sitting for +/-5 years. It had a fuel line rupture and am in process of rewiring. My concern is that the engine (327) may of froze up during its long sit in East Texas. I have heard of a product called "Mouse Milk" that can solve this, but I can't find it. This may be all for naught, but I wont know the engines status until the rewire is complete. Any input would be much appreciated.
