Hi jyrki! I am in the middle of building/rebuilding 3 engines, my ford exploder which "exploded", my 409 chev, and my 248 for my 50, along with beating nails into the house! The 248 is going to be a "take no prisoners" kind of build up and its sort of my test subject for the book as I do everything to this engine, it goes into the book. This has gotten rather into a bigger project than I initally thought! I've done a few papers but nothing like this! Main problem is that practly NOTHING is really known about these engines. I'm putting the finishing touches on the rod section, then its on to the crank. alleycat
