DiMora's 400 build - part deux
#166
I'm all fixed up.
I needed a new turn-signal switch assembly and complete harness. About $55.00 or so...brake lights work and the car is running like a champ. That 6AL ignition is awesome, and the new distributor is working just fine now. Still chapped that MSD charged me to fix a faulty distributor that had less than 2,000 miles on it, but it is what it is and it was outside of warranty under their rules (1 year).

I am also running the vac advance (but 28 is still the max).
I set the idle to 800 in neutral, about 650 when in gear.
TMeyer KB2344 -30 pistons (9.5:1 C/R with 302 Cleveland heads) (1.71 compression height, 30CC dish, .030 over)
Dynamic CR estimated to be in the neighborhood of 8.83:1 to 9.03:1
Cylinder pressure estimated 181-186 PSI

. Surprised you're still having a problem with pinging with your quench distance corrected and only 9.5:1... what distance did you end up with? 180 thermostat?
. An ounce or two of kerosene per tank of 93 will usually eliminate the pinging and allow a higher total advance... works for my 351W at 10.5:1 on iron heads... about same duration cam... 216/228... 36 degrees total...

I'm leaning toward running E85 on this car and buying a carburetor converted to run E85...and a fuel pump that can handle it...then I can turn the timing way up and get more power without pinging, Mwahaahaaaaa. Sure, you flow 30-40% more fuel, but it is cheaper than running 87 octane.
I might turn this beast into my daily driver and sell my 2007 Accord, LOL. I'm torn, but I do very much love driving this beast and if I am going to keep it, it needs to be used (driven) a lot more than it is right now.

It's funny reading all the issues you all have in using 302c heads on 400 builds. I had a totally stock 302c in a Aussie Falcon 25 years ago, was fitted with factory stock 2v intake with a Holley 350 on a adaptor.
(The 302c was fitted with a 2v intake from 1972 to 1977, then went to 4v)
Always had pinging issues under load and if I turned back timing it really became a slug of a engine.
Very sensitive to timing and running on after shutoff.

. Maybe the Aussie heads are like the Chevy Vortecs... make best power with only 28 - 34 degrees max timing (depending on other engine parts) because of the fast burn chambers... no more power from advancing it beyond that...
. The E85 needs about 15:1 compression ratio to become efficient... and with gas so much lower priced these days, and E85 losing 25% of MPG when compression ratio isn't boosted, there's not much reason to run it... and the alcohol in E85 won't always have its price Govt subsidized...
