sorry Chaplin for hi-jacking your thread but...
CJ428CJ
Your cam sounds similar to mine, and I also have a Holley 750cfm carb.(4150HP) I'm having a real hard time with it.
It runs so rich that at a stop light I have had 2 people on motorcycles ask if they could pass because my exhaust was burning their eyes.
What did you set your timing at?
Did you have the Demon carb custom built?
What's your compression? (mine = 10.5:1)
My 428 is at 36* total timing at 3,000rpms.
I think the problem is timing since above 3,000rmps
when all the timing is in, the sluggish, poor responce
dissapears. BUT I'm not ruling out that the carb. may
also be part of the problem. (Jets being too rich)
The last thing is, how do you learn how to optimize the distribuitor (sp)?
I can't help but to think that the weights/springs that control the advance of the timing my be out-of-wack for the motor. I did see a little oxidation on the surface of the weights an I'm concern.
Thanks for any help.
Todd
