I'd do a compression check. If its good then go a range colder on the plugs, back the timing back five to seven degrees and depending on A/F fattin it up a couple jets and try again. Once its dialed in for hi boost it's time to play!
Ya,all the above. Just ran a comp test and all appears good (within 2 lbs from previous test on all holes ). Valve train all looks good, including lash. Attached pic of plugs - NGK ZFR5F. Two burned ones were in holes 4 & 5. I'm open for suggestions on plugs? Could go a few steps colder - or maybe something that isn't an extended core? Already 5 sizes bigger on the jets all around - as I received the blower carb from ProSystems ( annular discharge 950 ). I could use some help with plug selection ( 408 blower motor with ported Magnums ).
Ah,Lucky. I think 25lbs might work intercooled. Would need less timing, 22-25? The super rich part I'm not convinced. Just as running a nitrous motor,way rich usually spells trouble. I've found 11.8-12.0 to work well. Mine always hurt #5.
