I am highly considering doing a resto mod for a 66-69 impala. I have found a few of these cars without the engine and transmission so I thought it would be perfect for restoring the body and interior but doing a modern V8 and manual tranny. I wanted to build the engine before I jumped into the car. I was considering a 350, 383, or 454 but honestly cannot decide which would be best. Any suggestions? I want a street car that I could really smoke some tires and turn some heads if I wanted, just some beefy American made muscle. Which should I go with?
