Well put. I was forming the exact thoughts into a reply when I saw this. Although I agree with RRR that the weight difference between a 360 and a 383 may only be about 150 pounds, that 150 pounds is right over the front wheels. And you certainly can lighten a 383 with aluminum parts, but you can do the same thing with a 360. You already have everything set up for a small block. I would go with a stroker motor. That is only my opinion, but that is what you wanted.
