Overheating wowes that make no sense - help!!!

33 degrees total is not enough advance for a healthy 440. I have been fighting the same problem and my machinist suggested more advance. I was running 220 and above with 36 degrees advance total and would shut it down at 230 cause I didnt want to hurt the motor before I figured it out. With 40 degrees total it runs at 200. This is a 500 with aluminum heads flagella and a stout solid roller cam at 10 to 1 that runs on 93 octane. Give it a shot. What ya got to loose?

Let us see. A 440 we just got back from Dvorack Machine won't go above 160. At 32 degrees, because that long stroke needs less timing. Search Dvorack, and see how many titles he holds. I have spent a lot of time with him, and have learned more than you can on line.
440, 32 degrees, then adjust for ping. Done. Take a 340 with good cam and heads; start at 36 total, then see where it whill idle. Mine at 18 degrees initial, so I pull out advance in the dist, to hold it at 36.
