What have you been doing since Aug 2005 Kevan?
Lurking, not posting?
Any idea of the compression for this beast?
Actually, the Performer cam at 218/228 deg dur @ .050is quite a bit more stout than the weenie stock hyd cam or the not-so-spectacular HP hyd cam 214/218
Before SWHEATON chimes in....I'll steal his thunder!
Disconnect the vacuum to the distributor, plug the carb. Check your base timing with idle set to 800 rpm. Factory spec is usually somewhere around 4-8* before top dead center.
Way low. You will probably want 36* total timing, all advance in by 3000 rpm. Your exact combo may like 12 initial plus 24 mech adv or
18 initial and 18 mechanical. Your combo sounds rather mild. You may need a shop to 'recurve' your distributor if you have a stock unit. Most aftermarket units have some tuning features.
Search "IGNITION 101" or any of Scott numerous posts on getting your timing set-up.
I learned most of this the hard way before Team Chevelle.....
I have had an Elelbrock Thunder AVS 800 several years. Best advice is to read the tuning instructions a few times....each carb comes with a set plus online
too much stuff for me to type, easier if you read and understand before digging in there.
Sadly, most users do not get friendly with their Eddy carbs...
There is ported and non-ported/direct vacuum. See this in the instruction manual.
Ported vacuum does not draw at idle so your timing does not change (much) unplugging the distributor compared to if the vacuum was hooked to direct vacuum.
My Eddy became clogged so the 3310 Holley went back on my car. The 3310 died the other day, so the repaired Eddy went back on. Later today, I'm gonna test my Eddy 800 vs a 4780 800DP Holley around town....
