Can someone help me identify the engine in my 67 lwb? I always thought it was a 283/powerglide truck, but now Im not sure if its a 283 or 327. The numbers on the front pad(passanger side) is VO6I3WE. I havnt been able to figure it out from this, and I cant see the rear number, due to a metal line in the way and a ton of oil and crud. Thanks
