Thanks for having me on the forum. My truck is a 1970 CST/10 2x4. Came with a 350/th350 combo from the factory but the original engine was long gone and had been replaced by a smog 305. Now its getting long rod 400 small block with gm serpentine drive and 700r4 auto. I will upload some photos of my build soon.Welcome from Washington state. What year is your truck? Any pictures?
