Well this time I thought I had it.. I hardly made a dent..
Fails with 81gpm CO and 7.9 GPM HC
Thats only 5gpm better on CO and 1gpm better on HC than last time.
What did I do to get readysince the last test?
replaced the Acell super coil with a new stock type
set timing to 10deg
replaced the 160 tstat with a 192
leaned out the carb again with .092main /.086 secondary jets .071x.047 rods
4hg springs (Edelbrock #1406 performer carb)
replaced fuel filter.
striped down the carb and cleaned it inside and out
re-routed all the vacuum lines to the correct locations (almost nothing was hooked up including the diverter valves for the air pump)
1/4 tank of 93 octane with a bottle of heat in it.
I'm thinking of really making a big jump leaner by trying a .086 jet on the primaries.
Some time soon I'll have to face the fact that the cats are probably toast.
One good thing.. they did it for free even though I was 16 days past the last test.
