422 dyno fail

That’s Funky.

For reference My current 340 is .30 over, with cleanup job of 2.02 J heads, at 10.2/1 with comp cams XE285HL in at 109 with 241/247 at .050, Holley 750 DP on top of a stock Eddy airgap and TTI headers. On the dyno after brake-in with over night cool down, and then warm up and 30 minute heat soak made 391 HP and 385 TQ on 91 pump gas. This was done on a known dyno in Portland that runs true to others in the Portland metro..
