Stock 49, I know what you mean when you say "Nothing has deterred me". I am the same way when it comes to using a intergrated cylinder head on my 250. IT would have been easy to transplant a 235/261/ or a later six into the 49. Can you please post the the mods done to the engine? Iknow about the stroker & the dual carbs but nothing else. Where can I get a copy of the Speed Manual? Thank you for the good opertunity to learn about these engines. My Aunt had a '50 powerglide 2 door that I remember riding in as a kid. Found out about a year ago that my cousin (who is still alive) got it as a first car! I will have to talk to him to find out more. Jay
