383 runs like a giant turd WTF

Remind's me of a 360 I built once. Similar deal. Poor runner. Could have gotten spank by a moped. Between the carb secondaries not fully opening, damper being off, (Stock one that moved, which also throws distributor timing off) and installed in the wrong key way on the timing chain...well, like I said, a moped could have taken me out. :violent1:
LOL, i've been there too, with a few different brands also...lol. Wasn't near the products or info. we have today. Was more of a learning experience. This particular engine looks old school to me so i'm looking forward to what the OP responds.
