Rob, wern't the 2bbl 383's rated 9 to 1 back then? I can remember the most minute specs on some things and others i have to question myself and actully research it. Although it was 40 yrs. ago....lol.
I do *think* so. I forget myself. I'm not so engrossed in the car world as I used to be. This is why I questioned the C-ratio. The 383's are finiky (sp?) much like the 318. They lack bottom end torque. A cam of the 292's size, which is a sizeable cam, can kill it dead quick. Installed wrong, just 2*& retarded will mess things up.
The 383 is a capable mill. Something is off with this build. More info is needed. We could be over looking something simple as well. 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:
