Help Gathering Info on Inherited Motor

Correct. You can try to sell it but I would not hold my breath. Jim at Racer Brown can grind you a smaller mechanical cam. I just got a ST-1 for my 68 Barracuda 383. 226 duration at .050 and .450 lift. Swap pistons, Ditch the Holley, get a Street Demon 750 carb and drop that thing in the Dart. Sell the parts you end up not using on here or eBay. No big deal. Drove my 68 383 anywhere anytime. They will run all day long at 100 mph. I have driven mine cross country with 0 problems.
That's exactly what I'm looking for. I just need to hear enough versions of what I need to do, so I can start reaching out to shops and talking to them about what exactly I'm hoping for. There's a lot of sentimental value in keeping the motor for me. I'd like to find out the most reliable and cost-effective way of doing so.
