hey as i said in the introduction section i needed help. In my CAD (we are using Autodesk Inventor 11) class we are doing a self paced design proposal and i would like to make mine the p-51 mustang engine (Merlin by Rolls-Royce). I've looked a lot online and have come short of finding any dimensions to build upon. Any dimensions that you have or know of would be a blessing to me and ill be sure to post pictures of the ending results if i can get the dimensions. If anyone knows of any this would greatly help me. If this is asking for too much i would more than greatly accept any other WWII plane engine dimensions. Many Thanks, Nick
