Real world notes for the thread:
4V Open - .012 deck, 214/224 hydro cam, 9:1 measured, 5500 shift point, 36 total timing, Autolite 25 plugs - no signs of detonation
2V open - .000 deck, 226/230 hydrocam, 9.5:1 measured, 6200 RPM shift point, timing locked @ 38 - slight specking on Autolite 25 plugs, clean on Autolite 24s.
4V closed - .000 deck, 238/248 solid flat, 10.5:1 measured, 6800 RPM shift, timing locked @ 38, Autolite 24s - clean plugs. Showing plug specks on that motor meant check the exhaust evac valves for failure.
302 - GT-40 iron head, 60cc chamber, 216/228 hydro cam, 5500 RPM shift, timing locked at 36. Engine was run at .012 deck, 9:1 - no detonation signs. Ran it a couple of seasons then pulled it down and zero decked the shortblock - no other changes, compression 9.5:1. Car picked up .2 and 2 MPH in the 1/8 from just the deck cleanup.
Note - I run/hold all our motors at 180~200F.
EDIT - based from 91 minimum, 93 better premium fuel. Cars are more consistent with 93 but will run on 91.
